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(). If the executed function calls interrupt_main the KeyboardInterrupt will be raised when the function returns. s 2nd arg must be a tuples 3rd arg must be a dictN( t typeR t tuplet TypeErrort kwargst dictt Falset _maint functiont SystemExitt _tracebackt print_exct Truet _interruptt KeyboardInterrupt( R R R ( ( R R s$ c C s t ‚ d S( s& Dummy implementation of thread.exit().N( R ( ( ( R R = s c C s d S( sò Dummy implementation of thread.get_ident(). Since this module should only be used when threadmodule is not available, it is safe to assume that the current process is the only thread.

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. c C s t | _ d S( N( R R t locked_status( R ( ( R R Y s c C sY | d j o t | _ d Sn8 | p# | i p t | _ t SqU t Sn t | _ t Sd S( s© Dummy 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.
