Because it is an internal helper for lock implementations that want to do optimistic spinning, it isn't a lock on its own and lacks several things you would expect. Using it is tricky and I don't trust random module authors to get 1+1 right, let alone use this thing correctly (no judgement on your code, just in general). > Here's what it's for: I'll try and have a look soon :-) But does that really _have_ to live in a module?
