Sounds much like the modes offered by an old operating system that had a very nice lock manager.

Awe, VMS isn't THAT old, is it? :-)

I have a wrapper around threading.Lock and threading.RLock that I've been using that does deadlock detection and have wished for these lock modes many times. I would hesitate to create a PEP to support this until I actually new I could pull it off.

I would be happy to share the code that I have with anybody that might find it useful, and welcome some help in implementing these modes.

There's one other very useful feature, and that was a callback from the lock manager when a lock that you held was blocking a request from some other process.
