This is getting into taste territory but sure just getting the signal in epoll_pwait removes the need for FD reading. But introduces the need for the thread local global context and the need to handle EINTR from epoll right? I can see how checking if signals were called in the EINTR-branch is nice though. Anyway nice to know the p-version use case.
