As a general comment: I used to think rwlocks were a simple extension to regular locks, but it turns out there's actually this huge increase in design complexity. Do you want your lock to be read-biased, write-biased, task-fair, phase-fair? Can you acquire a write lock if you already hold one (i.e., are write locks reentrant)? What about acquiring a read lock if you already hold the write lock? Can you atomically upgrade/downgrade a lock? This makes it much harder to come up with a one-size-fits-all design suitable for adding to something like the python stdlib. -n -- Nathaniel J.
