//       Class : ConditionVarFullDirect
// Description : A condition variable, usually used to communicate
//               information about changing state to a thread that is
//               waiting for something to happen.  A condition
//               variable can be used to "wake up" a thread when some
//               arbitrary condition has changed.
//
//               A condition variable is associated with a single
//               mutex, and several condition variables may share the
//               same mutex.
