I believe there are atleast two separate hangs that are being
experienced.  Both occur using ssh vs. the rsync:// protocol, but I
suspect that has something to do with the local pipe/socket to
communicate between the local rsync and ssh processes.

The first is the type described in this thread (Linux -> Windows) the
transfer starts and hangs at some point.  The second (Windows -> Linux)
which I reported as resolved using a local pipe vs. socketpair, hangs
immediately, ssh never gets as far as attempting network access.

Since the second never attempts network access, I suspect that Windows
-> Windows would hang, I haven't seen any reports of Linux -> Linux.  If
Linux -> Linux didn't work, I suspect the issue would be wide spread and
corrected.
