That makes sense.  Meanwhile, similar errors have unsurprisingly shown
up on the Hurd, but I'm not sure it supports either epoll or kqueue
anyway.

Natively, just kqueue, from <sys/event.h>.  I vaguely recall something
about an epoll compatibility library, but forget the details, and
anyway it's better to use kqueue if possible.
