panic "Sleeping thread owns a non-sleepable lock" via cv_timedwait_signal, was "rsync over NFS"

[Norbert Aschendorff]

Hehe, sure, if you assist me :)
I'm not very experienced with SVN, I'm actually a git user and I think
it's also better if I do /not/ express my opinion on SVN here ;)
The only actions I'm currently able to do in SVN are checkout, update,
commit and view log and status -- so any help is appreciated :P
