sense is that files, applications, libraries. etc., that happen to be
resident in memory will still work, but new accesses fail until the client
reboots.

When I looked into this problem earlier, I found that nbd-client has a
"-persist" option which seems like what is needed here.  I played around
with that, but I can't figure out how to actually get nbd-client started
with "-persist" on the client.  I added "-persist" to
/etc/init.d/nbd-client, but probably nbd-client is being started in some
other way, as "-persist" doesn't show up when looking at the command line
through the ps command.
