Me too. I'm using the standard version of rsync, so I guess the
socketpair call is still in use.

Not on my machine. ssh is a child process of rsync.
For tracking down, I would have wished to see that we could get a
*reproducible* testcase in which rsync over ssh hangs, to have
a chance to track down a potential problem in the Cygwin DLL which
might cause this. Even more welcome would be somebody who actually
debugs this situation inside of the Cygwin DLL, but that's becoming
more and more a futile dream.
