Things have not changed with regards to Python's threading
implementation in py3k.

If you want auto-locking with function calls, there isn't a keyword
that you can just pass, but there are these magical things called
decorators that allow the easy creation of synchronized decorators...

import threading

_lock = threading.RLock()
def synchronized(fcn):
    def call(*args, **kwargs):
        with _lock:
            return fcn(*args, **kwargs)
    return call


Used like:

class foo:
    @synchronized
    def method(self, ...):
        #because of the synchronized decorator, this method is now
protected by a lock
