Well... this implies that a condition is always associated with a mutex and 
that the Mutex concept provides a locked() query, which it currently does 
not.

In principle one may check for a try_lock failure, although this doesn't 
tell us which thread has locked the mutex.

Given that you already have a lock variable at the point you are calling 
wait, what's wrong with just passing it?
