Detailed Description

A intraprocess, reentrant lock/condition variable.

A monitor provides both (reentrant) mutual exclusion and thread cooperation via a condition variable.

Example of calling notify

* pMonitor->lock();
* some_condition = P6TRUE;
* pMonitor->notify();
* pMonitor->unlock();
* 

The thread being notified should be waiting like this:

* pMonitor->lock();
* while(P6FALSE == some_condition)
*   pMonitor->wait();
* pMonitor->unlock();
* 

It is important for the wait() method tobe called in the while loop testing the condition to prevent spurious wakeups on some platforms.
