Hmm... could be a bug on the OSX server as well?  On the client, if you do
an strace -p on the mount process, what do you see (when it's locked up).
Or maybe it's deadlocked waiting for some sort of IO?

Just brainstorming here, but maybe you could leave a tcpdump running and
catch this when it happens and see what part of the negotiation succeeded
and what part failed... perhaps help isolate whether the client or server is
to blame.
