Thanks, that's good to know. I should have tried it myself.
Using the snaphot 12/13/2005 build of cygwin1.dll it indeed works.

I believe this analysis is incorrect. If you examine the Perl script in the
example you will see that the call to open() never returns. Yes, the
windows executable is waiting for input (on a connected pipe), but it never
receives this input because the Perl script never advances past the open.
For what it's worth, this "used to work", at least on a very ancient cygwin
(1.5.3) / Perl (5.0.8) combination. Something along the way broke it, but
as reported above, it has apparently been fixed again.
Thanks for the feedback!
