It would, but keeping it in memory would be a bad thing.  Say your data.fs
file was 10GB large, and it took 4 hours to back it up, and you only had
X amount of RAM - then it would begin swapping after some time.  Now that
would be ugly :-).

One could possibly have a function that put new transactions in a new
file, and then - when told it was ok to do so - it could update the
regular data.fs file.  

Actually, if I'm not mistaken, this could be something to put in ZEO?
