This isn't correct because the incoming client can quit between the
time of poll() indicating its presence, and accept() trying to process
it. This is an expected non-fatal scenario, so it should just be
ignored without quitting. epoll_ctl() by comparison is a fatal system
error, so has to be handled as an unrecoverable error
