Precedence: bulk

scenario: /home/mikeg of desktop box mounted by lappy, lappy sitting
idle with user mikeg not even logged in.  Reclaim inducing activity on
desktop box eventually leads to spew below.  I've hung the box three
times in two days, twice with light client side activity, and below
with none, ie with the mount point allegedly merely existing. Sans nfs
mount, box seems perfectly fine. 6.1 didn't reproduce either, so it
would appear to be a merge window bug.
