pre-exec works in XP but not in Vista

[Matthias Meyer]

I run a sshd as well as a rsyncd within cygwin in both, in WindowsXP as well
as in Windows Vista.
Strange to say, pre-xfer will work in XP perfectly but in Vista only after a
previously login through sshd.
Strange too, that sshd use bash.exe and pre-xfer use sh.exe which is a copy
of bash.exe.
Without a previously login through sshd the forked rsync process will hang.
If I do remove sh.exe, rsync will log an error (256). But if sh.exe is in
place rsync will hang. Wait for sh.exe?

Werfault.exe is running, I believe to report the following error, which I
found in "Control Panel->System and Maintenance->Problem Reports":
Produkt
sh.exe
