This thread's subject line is a reply to my original posting in
December of last year:

http://www.cygwin.com/ml/cygwin/2005-12/msg01096.html

Rereading that posting, I was able to get rsync over ssh to work
reliably by changing rsync to use a pipe vs. a socketpair.  This
solution uses socketpairs instead of pipes.

I'm wondering if there are two pipes/socketpairs?  My read is that
each of the two solutions, essentially matches one to the other.  That
is changing OpenSSH to use socketpairs, matches to rsync's use of
socketpairs and visa versa.
