I don't understand why PGSemaphoreTimedLock() is not broken.  I mean
surely you need a bool return to let the caller know whether the
acquisition succeeded or failed?  AFAICS you are relying on
get_timeout_indicator() but this seems to me the wrong thing to do ...
(not to mention how ugly it is to percolate through two levels of
abstraction)
