That's really cool, but I don't see how it can be a pure userspace operation if the futex has a timeout. The kernel must need to keep track of the timeouts. However, since futexes can be woken by any thread, the whole thing can be done with just one futex. In fact the doc mentions something about using a file descriptor to support asynchronous wakeups, but it's confusing whether that applies here. -- http://mail.python.org/mailman/listinfo/python-list
