instead of "abort" I should have said "limit" because
it is really proactive control (so they will not get
called in the middle of the night by pissed users).

I forgot to make it clear that TIMEOUT is the same as AUTO-THAW
in logging errors so the adnin knows they have a bad snapshot and
can do it again.

I also forgot to say that our customers all say they can deal
with retrying a snapshot, but not with unknown bad snapshots
and most definitely not with killing their 24/7 operations!
