You are just having wrong expectations. Releasing a lock doesn't guarantee that any other thread waiting on it will be scheduled preemptively. So, if you re-acquire the lock immediately, the other thread will not necessarily have had the opportunity of running at all. Whether or not threads do get switched at that point is highly system-dependent.
There are many synchronisation primitives you can use (locks, events, queues, condition variables...), each for a different purpose. I suggest you post on comp.lang.python if you want more help on the subject.
