kgio provides non-blocking I/O methods for Ruby without raising
exceptions on EAGAIN and EINPROGRESS. It is intended for use with the
Unicorn and Rainbows! Rack servers, but may be used by other
applications.

Changes:

This release fixes a race condition that could allow
Errno::EINTR to be raised even though the 2.4.0 release
was supposed to stop that.

Nobody uses Kgio.poll, really, so this shouldn't be an issue
for real code, yet.
