Since we have EPOLL_CTL_DEL implemented for the poll(2) and kqueue backends, we can rely on Perl refcounting to gently close(2) the underlying file descriptors as references get dropped. This may be beneficial in the future if we want to drop a descriptor from the event loop without actually closing it.
