//       Class : ConditionVarFull
// Description : This class implements a condition variable; see
//               ConditionVar for a brief introduction to this class.
//               The ConditionVarFull class provides a more complete
//               implementation than ConditionVar; in particular, it
//               provides the signal_all() method, which is guaranteed
//               to wake up all threads currently waiting on the
//               condition (whereas signal() is guaranteed to wake up
//               at least one thread, but may or may not wake up all
//               of them).
//
//               This class exists because on certain platforms
//               (e.g. Win32), implementing signal_all() requires more
//               overhead, so you should use ConditionVar for cases
//               when you do not require the signal_all() semantics.
//
//               There are still some minor semantics that POSIX
//               condition variables provide which this implementation
//               does not.  For instance, it is required (not
//               optional) that the caller of signal() or signal_all()
//               is holding the condition variable's mutex before the
//               call.
//
//               This class inherits its implementation either from
//               ConditionVarFullDebug or ConditionVarFullDirect,
//               depending on the definition of DEBUG_THREADS.
