Content
There was a recent buildbot failure on test_lock_conflict() because of a race. Looking at your patch, I must be missing something, but why not simply use a multiprocessing condition to signal when the parent process has acquired the lock? Otherwise you could simply use a pipe or a socketpair, it would be much simpler. Also, there's a race: if the parent process calls connect() before the child calls listen(), he'll get ECONNREFUSED.
