You may be seeing the classic "cygwin rsync hang" problem:
http://www.cygwin.com/ml/cygwin/2003-10/msg01807.html
The problem arises because Cygwin's select() indicates "OK to write"
on pipes even when the pipe is full and the write will block. The
write blocks even though the pipe is flagged O_NONBLOCK.
Bob Byrnes, who did the diagnosis above (and who is a coworker of
mine) has patched our local copy of Cygwin to implement proper
select() for writing on pipes, as well as to fix some other hangs. He
is working on getting the patches and documentation into shape for
submission.
