// This class provides mutex resource management in a guaranteed and    //
// exception safe way. Use like this:                                   //
// {                                                                    //
//    TLockGuard guard(mutex);                                          //
//    ... // do something                                               //
// }                                                                    //
// when guard goes out of scope the mutex is unlocked in the TLockGuard //
// destructor. The exception mechanism takes care of calling the dtors  //
// of local objects so it is exception safe.                            //
