cygwin 1.7.x rsync 3.0.6 hangs at arbitrary reproducible points in transfers

Since upgrading to cygwin 1.7.x, I'm unable to complete rsync jobs to a 
Debian machine (running stable). cygwin rsync is 3.0.6; Debian is 3.0.3.

The transfer goes for a while and then just gets stuck halfway through 
an arbitrary file. If I cancel and restart, same thing (but gets a 
little further). If I manually copy the file in question, it will 
usually go a bit longer and then get stuck somewhere else.

I've seen a few postings on this list recently about similar issues, but 
no suggestions have worked. (In particular, some have suggested this is 
a problem with older cygwin/rsync, but it only started for me with 
cygwin 1.7.x).

I've posted cygcheck and strace output here:

http://adam.rosi-kessel.org/bugs/rsync/

Here are the last few lines of the strace in one example run. At the end 
is where it is just hung. This is from the cygwin side.

cygwin 1.7.x rsync 3.0.6 hangs at arbitrary reproducible points in transfers

Hi,

I am having the exact same problem on a Windows platform. I have been using
(prior versions of) rsync without any problems for a few years now.

Any help towards solving this problem greatly appreciated.

My logs are available upon request.

Regards,
Alan
