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 typet tuplet TypeErrort dictt Falset _maint SystemExitt _tracebackt print_exct Truet _interruptt KeyboardInterrupt( t functionR t kwargs( ( s$ /usr/lib64/python2.7/dummy_thread.pyR s c C s t � d S( s& Dummy implementation of thread.exit().N( R ( ( ( s$ /usr/lib64/python2.7/dummy_thread.pyR : s c C s d S( s� Dummy implementation of thread.get_ident().

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 t locked_status( R ( ( s$ /usr/lib64/python2.7/dummy_thread.pyR \ s c C s= | d k s | r t | _ t S| j s5 t | _ t St 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.
