This is probably the same error as the one that I had when
using rsync in cygwin-1.7. It is probably caused by some
firewall or anti-virus software blocking the operation of
rsync. In my case, the culprit was NOD32.

	When I ran rsync in gdb,

$ mkdir somedir
$ touch somedir/somefile
$ gdb --args /usr/bin/rsync -a somedir/ anotherdir
GNU gdb 6.8.0.20080328-cvs (cygwin-special)
.....

(gdb) run

	I have had no problems with rsync in cygwin-1.5 and
NOD32. There must be some changes in the implementation of
socket/IPC/pipe between cygwin-1.5 and -1.7, which NOD32
does not like. I did not track it down further because
this is a problem of NOD32 and because the workaround was
simple: add rsync to the exception list of NOD32.
