I will try to alter it this way. However, there is no easy way of testing such case, apart from compiling specially crafted linux program. Also forking after poll is a marginal case. Doubt it ever matters in practice. I found two more problems with the patch: epoll_wait treats timeout as if it was in microseconds, when it is in milliseconds. Also epoll_wait doesn't check for the special case of timeout=-1. I corrected both issues. Will do additional testing, and will submit PR with an updated patch when done.
