A thought I've had is that you could get a 'point in time' view with the
current FileStorage by simply stopping reading after X bytes - since the
file is just appended to, this will show the ZODB as it was at that state.

From the UML models, tho, the FileStorage doesn't write down a timestamp
with each transaction - ah, but Mr SourceCode says that the transaction
ID is a timestamp. Exceeellent.

Sure, you'd want to make it a readonly view, but it could still allow some
recovery for when someone's made a godawful screwup.
