- * Port locking:
- *
- * Locking is done either driver specific or port specific. When
- * driver specific locking is used, all instances of the driver,
- * i.e. ports running the driver, share the same lock. When port
- * specific locking is used each instance have its own lock.
- *
- * Most fields in the Port structure are protected by the lock
- * referred to by the lock field. I'v called it the port lock.
- * This lock is shared between all ports running the same driver
- * when driver specific locking is used.
- *
- * The 'sched' field is protected by the port tasks lock
- * (see erl_port_tasks.c)
- *
- * The 'status' field is protected by a combination of the port lock,
- * the port tasks lock, and the state_lck. It may be read if
- * the state_lck, or the port lock is held. It may only be
- * modified if both the port lock and the state_lck is held
- * (with one exception; see below). When changeing status from alive
- * to dead or vice versa, also the port task lock has to be held.
- * This in order to guarantee that tasks are scheduled only for
- * ports that are alive.
- *
- * The status field may be modified with only the state_lck
- * held when status is changed from dead to alive. This since no
- * threads can have any references to the port other than via the
- * port table.
