I've been tracking down a problem in xinetd. It appears to be an issue

Yes, that's a bug in Cygwin. The socket event handling got messed up
when MSG_PEEK was used. I fixed that in CVS so it will be in 1.7.2.
The last time I had problems with MSG_PEEK was back in 2006. Curious
how seldomly it's used, apparently.
Thanks for the simple testcase! It was very helpful to track down
the problem easily.
I wonder if rsync uses MSG_PEEK? If it does, could this explain the
rsync spinning problem that gets fixed (for me anyway) by not using
socketpair?
