Meant to be used as a brain-dead substitute so that threaded code does not need to be rewritten for when the thread module is not present.

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. z2nd arg must be a tuplez3rd arg must be a dictFNT) typetuple TypeErrordict_main SystemExit traceback print_exc _interruptKeyboardInterrupt)Zfunctionargskwargsrr8C:\ALexclude\prg\programme\Python37\Lib\_dummy_thread.pyrs cCstdS)z'Dummy implementation of _thread.exit().N)rrrrrr=scCsdS)zDummy implementation of _thread.get_ident().

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.
