That's a typical Cygwin fork problem and has nothing to do with ruby.
You'll need to take this up with the Cygwin mailing list.  You can add
your voice to the chorus of people experiencing this class of problem. :-/

There are various workarounds you can try that may or may not work for
you.  Common solutions are to disable/remove certain applications such
as certain AV software and some video drivers that bind into the guts of
Windows and disrupt Cygwin (see BLODA -
http://cygwin.com/faq/faq.using.html#faq.using.bloda), running
rebaseall, and shutting down memory hungry applications such as Firefox.

If you're on Win7 64-bit, you're in the same boat as me.  The Cygwin
devs are working on hacking better support for that platform, and you
may have luck with one of their recent snapshot builds.

Good luck!
