What happens if you run the test program I posted yesterday after the changes?
It looks like pselect() and epoll_pwait() operated completely differently.
pselect() would always calls the signal handlers.
epoll_pwait() only calls them when EINTR is returned.
So changing epoll_pwait() and pselect() to work the same way
is bound to break some applications.
