All the machines were running NFS in default mode, which means UDP.  I 
have been running this way for years without any problems, until just 
recently when it broke hard.  Perhaps it was just coincidence, but at 
first it broke only on the single machine on which I run IPNAT, and it 
broke immediately after a new version of IPNAT was imported.  Just bad 
timing, I guess, cuz a few days later it then started breaking on the 
laptop!

I've since changed everything to TCP, and everything is once again 
happy.

In my case, it was emminently reproducible, nearly 100%.  And it only 
affected _one_ of the NFS volumes mounted on the afflicted machine;  the 
other NFS volumes had no issues _most_of_the_time_!
