Actually it should have been improved a bit lately. Venus used to keep
the kernel device open when it crashed, and the kernel would keep on
trying to post upcalls to a dead venus. Venus now closes /dev/cfs0 when
it goes down, so that the kernel can return EIO on all attempts to
access /coda.

Ofcourse if venus isn't crashed it might be either, timing out on
server probes, or the thread hits a Wait() when it enters a volume with
a CML that is owned by another user. Still have to look into why it does
