Thanks for the strace.  This + our irc chat allowed me to duplicate the
problem.  It should be fixed in the next snapshot which is building now.

I'd be surprised that this would work on 1.5.x since it relied on cygwin
honoring nonblocking writes on pipes which, AFAIK, we never have done
right.  We can do it better in 1.7.x though and the change I just made
seems to prove that.
