public interface IMutex
extends Lock

A mutex (=mutual exclusion) is the special case of a semaphore. A mutex has got only two states, locked and not locked. A lock can be only held by one thread at the same time. If a lock provider supports deadlock detection, than the provider should throw a DeadlockException in case of a deadlock.
