Well, it had been around an hour and a half on this occasion. Next time
it happens I can wait longer but I'm pretty sure I've come back from
time away and it's been wedged for at least a day. How long would you
expect it to remain in this state for?

It's a mythtv box so at times where no one is watching anything and
there isn't anything to record I expect NFS activity is pretty minimal.

Can anyone remember when the times were not hard, and money not scarce?
