It's not clear to me from the Python docs whether waitflag is treated as a boolean or as a number.
Running on Windows, I get two different behaviors from the following calls to acquire: aLock = threading.Lock() ... # Thread 0 # This one often succeeds aLock.acquire(1) ... # Thread 1 # When this one would fail in a different thread aLock.acquire(2) but the behaviors aren't what I would expect if waitflag were a timeout value. If the argument to acquire is a true/false flag, the behaviors for values of 1 and 2 ought to be the same. If it's not a true/false flag, what is it? It's not clear to me that it's a timeout value - wait this many seconds and then fail if the lock can't be acquired. What I really need is a timed lock - which I can implement myself by calling acquire(0) and sleeping and looping for some time until it succeeds or times out. But if Python already supports this, I'd rather do it the Python way. Thanks. -- http://mail.python.org/mailman/listinfo/python-list
