Ok, sounds good, although I have no idea what might have plugged
the leak. (I looked at the revision log for clnt_dg.c and udp_usrreq.c
and I couldn't spot anything that might have fixed an mbuf leak.)

As for the "can't unmount", I assume that it reports the mount pt
as busy? (I've never seen this for the exp. client, so I have no idea
what the cause might be for this. Possibly some "failure" code path
that lacks a vput()/vrele() that I've never exercised?)

Anyhow, good to hear about the above, rick
