00025 //       Class : ConditionVarFullDebug
00026 // Description : A condition variable, usually used to communicate
00027 //               information about changing state to a thread that is
00028 //               waiting for something to happen.  A condition
00029 //               variable can be used to "wake up" a thread when some
00030 //               arbitrary condition has changed.
00031 //
00032 //               A condition variable is associated with a single
00033 //               mutex, and several condition variables may share the
00034 //               same mutex.
