Indeed. I have been seeing this as well. An NFS mount becoming unavailable
for an extended time, processes hang because of the hard mount (maybe it is
a good idea to allow processes to be killed using -SIGKILL even if hanging
on a hard mount? I mean, even if the NFS server wakes up again, and the
process proceeds, all that could happen would be for it be killed instantly;
so we might as well kill it immediately and be done with it), and the
NFS server comes back up, but the processes keep lingering around in a hung
state.

You are currently aboard a fully automated plane. There is no pilot on board.
Rest assured, you have nothing to worry about... worry about... worry about...
