I have just performed a test of what you describe, using 'smbtest'
(6.1-STABLE #17: Fri Aug 25 12:25:19 CEST 2006) as the client and
'data-2' (FreeBSD 6.1-STABLE #16: Wed Aug 9 15:38:12 CEST 2006) as the
server.

Which is to say that it completed successfully. Which suggests that there
is not a serious and ongoing problem.
Hm. That's a useful data point: thanks for making the test!
What about the non-interruptible sleep? Is this regarded as par for the
course with NFS, or as a problem?
I know that "hard" NFS mounts are treated as completely unkillable, though
why `kill -9` isn't made to work escapes me, but a locking operation which
(presumably) suffers a protocol error? Or is rpc.lockd simply waiting to
hear back from the (presumably broken) NFS server? Even so: `kill -9`
ought to work!
