eaead„Zd	S(s,Drop-in replacement for the thread module.

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.

Suggested usage is::

    try:
        import thread
    except ImportError:
        import dummy_thread as thread

t‚ndS(säDummy implementation of thread.start_new_thread().

    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.

    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.  Thus a constant can be safely returned.

    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.

        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.
