Class Description

                                                                      
 TMutex                                                               
                                                                      
 This class implements mutex locks. A mutex is a mutual exclusive     
 lock. The actual work is done via the TMutexImp class (either        
 TPosixMutex, TSolarisMutex or TNTMutex).                             
                                                                      


TMutex(Bool_t recursive)
 Create a mutex lock. The actual mutex implementation will be
 provided via the TThreadFactory.

Int_t Lock()
 Lock the mutex. Returns 0 when no error, 13 when mutex was already locked
 by this thread.

Int_t TryLock()
 Try to lock mutex. Returns 0 when no error, 13 when mutex was already
 locked by this thread.

Int_t UnLock()
 Unlock the mutex. Returns 0 when no error, 13 when mutex was already
 locked by this thread.

Int_t CleanUp()
 Clean up of mutex if it belongs to thread.
