Compatibility is maintained by maintaining self.locked_status which is a boolean that stores the state of the lock.

For blocking calls, self.locked_status is automatically set to True and returned appropriately based on value of ``waitflag``. If it is non-blocking, then the value is actually checked and not set if it is already acquired. This is all done so that threading.Condition's assert statements aren't triggered and throw a little fit.
