Class Description

 This class provides an interface to the posix condition variable     

TPosixCondition(TMutexImp *m)
 Create Condition variable. Ctor must be given a pointer to an
 existing mutex. The condition variable is then linked to the mutex,
 so that there is an implicit unlock and lock around Wait() and

 TCondition dtor.

Int_t Wait()
 Wait for the condition variable to be signalled. The mutex is
 implicitely released before waiting and locked again after waking up.
 If Wait() is called by multiple threads, a signal may wake up more
 than one thread. See POSIX threads documentation for details.

Int_t TimedWait(ULong_t secs, ULong_t nanoSecs)
 TimedWait() is given an absolute time to wait until. To wait for a
 relative time from now, use TThread::GetTime(). See POSIX threads
 documentation for why absolute times are better than relative.
 Returns 0 if successfully signalled, 1 if time expired.

Int_t Signal()
 If one or more threads have called Wait(), Signal() wakes up at least
 one of them, possibly more. See POSIX threads documentation for details.

Int_t Broadcast()
 Broadcast is like signal but wakes all threads which have called Wait().
