Compatibility is maintained by making sure that ``args`` is a tuple and ``kwargs`` is a dictionary. If an exception is raised and it is SystemExit (which can be done by _thread.exit()) it is caught and nothing is done; all other exceptions are printed out by using traceback.print_exc().

Compatibility is maintained by maintaining self.locked_status which is a boolean that stores the state of the lock. Pickling of the lock, though, should not be done since if the _thread module is then used with an unpickled ``lock()`` from here problems could occur from this class not having atomic methods. cd|_y)NF locked_statusr s rrzLockType.__init__fs "rNcx||rd|_y|jsd|_y|dkDrddl}|j|y)aDummy implementation of acquire(). 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.
