 I've had problems running the cache on ext3... :-( Haven't
checked in a couple of months , since I'm now using ext2
exclusively for my cache, but what happened was that I got
kernel and/or cache manager crashes on boot after a ext3
recovery. My guess at the time was that the ext3 file integrity
check got some borken cache files back back in order good enough
for the cache manager to try to use them, but not good enough
for them to be usable, where ext2 just failed for some of them,
stopping the cache manager from even try the borken cache files,
and thus ending up with behaving better.

Also, yet again, can't say that this behaviour still is there,
it might have been something in either the cache manager or in
ext3 that is now fixed. (Or something in my setup for that
matter...)
