We're about to open source a similar deal (redis-based "soft guarantee" mutexes) -- ours is written in Python and mostly used as a way to coordinate (very frequent) parallel task execution a la CountDownLatch, so 100% reliable exclusion in the face of failure isn't critical. I'd be interested to hear about your implementation if you can share (email is HN username at gmail.com)
