bpo-30643: Fix race condition in signal wakeup in forkserver (followup to PR #1989) (#2139)
* Fix race condition in signal wakeup in forkserver (followup to PR #1989)
There's an admittedly well-known race condition where ECHILD can arrive
just before the C function epoll_wait() and the latter wouldn't therefore
return EINTR. The solution is to use set_wakeup_fd(), which was designed
to avoid such race conditions.
* Reset wakeup fd in child
