sleepy_penguin provides access to newer, Linux-only system calls to wait
on events from traditionally non-I/O sources. Bindings to the eventfd,
timerfd, inotify, and epoll interfaces are provided. Experimental support
for kqueue on FreeBSD (and likely OpenBSD/NetBSD) is also provided.

* [PATCH] kqueue: ensure close-on-exec flag is set

Calling IO::new apparently does not set the close-on-exec flag
in Ruby 2.x (tested with 2.2.6 on FreeBSD), so we must set it
ourselves.
It's not a huge deal to be missing close-on-exec for kqueue,
since kqueue already has close-on-fork behavior(!) and it's rare
for a process using kqueue to exec without forking, first.
