The problem on Cygwin is the parent fails to kill the child at the end of a receive. Without finding the root-cause (I don't know about cygwin internals), I rearranged the code around the msleep loop to create a patch did solve the problem for me: http://lists.samba.org/archive/rsync/msg06500.html But several other people have reported that it didn't help. Following that, Anthony Heading came up with a new patch that used an additional pipe, instead of a signal, to tell the child to exit: http://lists.samba.org/archive/rsync/msg06501.html with a diff -u patch here: http://lists.samba.org/archive/rsync/msg06527.html James Tillman reported that this fixed his hang problem on Cygwin. But JW noted this produced an error in regression testing: http://lists.samba.org/archive/rsync/msg06615.html and then he provided an improved patch: http://lists.samba.org/archive/rsync/msg06624.html and Lapo Luchini came up with a test package with the patch: http://lists.samba.org/archive/rsync/msg06625.html but noted it failed make check. Shortly after that point the thread died. The basic approach in the patch looks sound. Unfortunately I haven't had the time to follow through on these patches. Plus my test case that used to create a hang isn't easy to replicate for me.

Why don't you try JW's last patch above? Something close to this should be a reliable fix.
