[issue1554] nfs stall

["Thomas Nikolajsen \(via DragonFly issue tracker\)" <sinknull@xxxxxxxxxxxxxxxxxxxxx>]

New submission from Thomas Nikolajsen <thomas.nikolajsen@mail.dk>:

dfly 2.4.0

'git gc' stalled (host didn't freeze) after some
'nfs server .. not responding' / '.. is alive again'
git repo on nfs mounted dir on local host.
Other commands using nfs mount also stalls.

Same experience with nfs mounted on remote host.
(have seen this a few times over the last ~2 months,
was guessing problem was network HW (although ping did respond))

(did `shutdown' shortly before escape to debugger;
it didn't seem to shutdown: returned to shell prompt;
can do other core dump if needed)

'git gc' did succeed using local fs (hammer) directly (no nfs).
Can reproduce, as prev. state of git repo is in snapshot.

Core dump *.39 uploading to leaf.
