Nope, it's just mundane packet loss.  For some reason, about half of all
mount attempts just get lost.  If I run tcpdump on both ends, when the
mount fails, the client sends two packets right away, and two more a while
later, and none of them get through to the other side.  It doesn't appear
to ever recover - but if I restart it, it sometimes works.

No packets other than NFS mount and unmount requests are staying lost.

It appears that "mount_nfs -T" still implies udp for the mount protocol
itself.  I don't suppose there's a way to override this?
