I was thinkng about using the following approach - performing a pack,
and backing up a .old file, while the work may continue with the new
.fs file. Does this sound reasonable, or am I missing something
crucial? This is running under ZEO, so its not feasible to warn
all the users 'stop working, I'm running backup'. If there is a way
to perform a hot backup remotely, from the client machine,
that would be even better.

As a side question: what would be the correct way to shut ZEO down?
ATM I'm just killing the server process, is there a less rude way to
perform a clean shutdown?
