mutex
     
         A {mutual exclusion} object that allows multiple
        {threads} to synchronise access to a shared resource.  A mutex
        has two states: locked and unlocked.  Once a mutex has been
        locked by a thread, other threads attempting to lock it will
        block.  When the locking thread unlocks (releases) the mutex,
        one of the blocked threads will acquire (lock) it and proceed.
     
        If multiple threads or tasks are blocked on a locked mutex
        object, the one to take it and proceed when it becomes
        available is determined by some type of scheduling algorithm.
        For example, in a priority based system, the highest priority
        blocked task will acquire the mutex and proceed.  Another
        common set-up is put blocked tasks on a first-in-first-out
        queue.
