+
+/*
+ * ------ 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!
