Not really in this case...  There are a load of VMware VMs running,
and it seems that they are using fairly short-lived threads to 
do the writes.  The log messages refer to vmware-vmx(1234), say,
but when I check what PID 1234 is with ps H | grep 1234, I don't 
find anything.

It could well be a problem between keyboard and chair, but
the immediate panic is over, so I'll have to leave this
for now.

Later,
