+ * Description: An "address order first fit" allocator
+ * based on a Red-Black (binary search) Tree. The search,
+ * insert, and delete operations are all O(log n) operations
+ * on a Red-Black Tree.
+ * Red-Black Trees are described in "Introduction to Algorithms",
+ * by Thomas H. Cormen, Charles E. Leiserson, and Ronald L. Riverest.
+ *
+ * This module is a callback-module for erl_alloc_util.c
+ *
+ * Algorithm: The tree nodes are free-blocks ordered in address order.
+ * Every node also keeps the size of the largest block in its
+ * sub-tree ('max_size'). By that we can start from root and keep
+ * left (for low addresses) while dismissing entire sub-trees with
+ * too small blocks.
+ *

+ * ------ Usage instructions -----------------------------------------------
+ *
+ * This module keeps track of the progress of a set of managed threads. Only
+ * threads that behave well can be allowed to be managed. A managed thread
+ * should update its thread progress frequently. Currently only scheduler
+ * threads and the aux_thread are managed threads. We typically do not want
+ * any async threads as managed threads since they cannot guarantee a
+ * frequent update of thread progress, since they execute user implemented
+ * driver code.
+ *
+ * erts_thr_progress_current() returns the global current thread progress
+ * value of managed threads. I.e., the latest progress value that all
+ * managed threads have reached. Thread progress values are opaque.
+ *
+ * erts_thr_progress_has_reached(VAL) returns a value != 0 if current
+ * global thread progress has reached or passed VAL.
+ *
+ * erts_thr_progress_later() returns a thread progress value in the future
+ * which no managed thread have yet reached.
+ *
+ * All threads issue a full memory barrier when reaching a new thread
+ * progress value. They only reach new thread progress values in specific
+ * controlled states when calling erts_thr_progress_update(). Schedulers
+ * call erts_thr_progress_update() in between execution of processes,
+ * when going to sleep and when waking up.
+ *
+ * Sleeping managed threads are considered to have reached next thread
+ * progress value immediately. They are not woken and do therefore not
+ * issue any memory barriers when reaching a new thread progress value.
+ * A sleeping thread do however immediately issue a memory barrier upon
+ * wakeup.
+ *
+ * Both managed and registered unmanaged threads may request wakeup when
+ * the global thread progress reach a certain value using
+ * erts_thr_progress_wakeup().
+ *
+ * Note that thread progress values are opaque, and that you are only
+ * allowed to use thread progress values retrieved from this API!

+ * Description: Lock-free queue for communication between threads.
+ *
+ * Currently only a many-to-one version has been,
+ * implemented, i.e., many threads can enqueue but
+ * only one thread can dequeue at a time. It doesn't
+ * have to be the same thread dequeuing every time, but
+ * synchronization so that only one thread dequeues
+ * at a time has to be provided by other means.
+ *
+ * When/If the need for a many-to-many queue arises,
+ * this implementation can relatively easy be extended
+ * to support that too.
+ *
+ * Usage instructions below.
+ *
+ * Author: Rickard Green
+ */
+
+/*
+ * ------ Usage instructions -----------------------------------------------
+ *
+ * Dequeuing generates garbage that needs to be cleaned up.
+ * erts_thr_q_dequeue() automatically cleans, but garbage may have to be
+ * cleaned up also when the queue is empty. This is done by calling
+ * erts_thr_q_clean(). In the SMP case thread progress may have to be made
+ * before cleaning can continue. If so, erts_thr_q_need_thr_progress() in
+ * combination with erts_thr_progress_wakeup() can be used in order to
+ * request a wakeup at appropriate time.
+ *
+ * Enqueuing implies memory allocation and dequeuing implies memory
+ * deallocation. Memory allocation can be moved to another more suitable
+ * thread using erts_thr_q_prepare_enqueue() together with
+ * erts_thr_q_enqueue_prepared() instead of using erts_thr_q_enqueue().
+ * Memory deallocation can can be moved to another more suitable thread by
+ * disabling auto_finalize_dequeue when initializing the queue and then use
+ * erts_thr_q_get_finalize_dequeue_data() together
+ * erts_thr_q_finalize_dequeue() after dequeuing or cleaning.
+ *
+ * Ending the life of the queue using either erts_thr_q_destroy()
+ * or erts_thr_q_finalize() impies cleaning the queue. Both functions
+ * return the cleaning result and may have to be called multiple times
+ * until the queue is clean. Once one of these functions have been called
+ * enqueuing is not allowed. This has to be synchronized by the user.
+ * If auto_finalize_dequeue has been disabled, the finalize dequeue
+ * functionality has to be called after ending the life of the queue just
+ * as when dequeuing or cleaning on a queue that is alive.
+ *

+ * Description: Lock-free queue for communication between threads.
+ *
+ * Currently only a many-to-one version has been,
+ * implemented, i.e., many threads can enqueue but
+ * only one thread can dequeue at a time. It doesn't
+ * have to be the same thread dequeuing every time, but
+ * synchronization so that only one thread dequeues
+ * at a time has to be provided by other means.
+ *
+ * When/If the need for a many-to-many queue arises,
+ * this implementation can relatively easy be extended
+ * to support that too.
+ *
+ * Usage instructions can be found in erts_thr_queue.c
