Comment (by vorner):

 I don't think that the implicit acquiring and releasing is a problem. Or
 do you
 mean some other one than it is released when you do wait and acquired
 again
 before the wait terminates? I think this would work (provided the Mutex
 adds
 some kind of friend declaration for the condition):

 {{{#!c++
 Mutex mutex;
 CondVar condvar(mutex);

 void
 doSomething() {
         Mutex::Locker locker(mutex);
         …
         // Make sure we have enough of X
         while (X < enough) {
                 condvar.wait();
         }
         …
 }
 }}}
