[ZODB-Dev] Who's experiencing FileStorage corruption?

I didn't ask for any, but I'm not complaining <wink>.  After some quality
time with Google, I have the impression that FileStorage is getting a bum
rap in some circles.

That's a match to Zope Corp's experience, and thanks for confirming that
FileStorage users aren't generally plagued with corruption problems!  Since
(as you know) a FileStorage always grows by appending, it's hard to imagine
how clumps of NUL bytes can end up in the interior except via non-ZODB
system problems (although I remain open to the possibility that ZODB is at
fault).
