Summary: sleepy_penguin 3.3.0 - fixes and compatibility improvements
Project: Rainbows!

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) are also provided.

Changes:

Most notably, this fixes memory leaks for any users of inotify
reads, epoll/kevent waiting using short-lived thread. Users of
long-lived threads for these functions (all Rainbows!, yahns, and
zbatery users) are not affected. A fair amount of internal cleanup
was necessary for this.

Compatibility with non-Linux systems without clock_gettime is
improved, thanks to Lin Jen-Shin.

Note: the kevent code is not at all optimized and still uses
RARRAY_PTR, so it likely sucks under rbx and MRI 2.1.
