Then you have to convince me (you don't have, but I won't believe you)
that this is a problem... surely, each ~8MB chunk of a large file is
fragmented on an ext2 file system _by definition_, but these are very

I think that on an OS that encourages fragmentation you are
right. However, I can't think of a common os in use that allows to run
gimp and has such a bad filesystem.

But this is not at all a problem. For example, on my 8GB main (i.e. /usr,
/home) partition that I already use since two years ans that is 95% full
(too full for the file system in question) I have 0.5% fragmentation. Only
two files have fragmented chunks smaller than 8MB (the maximum).
In any case, since you think this is bad (and I think this is good), only
hard data would clear this problem.
However, as a matter of fact, linux' swapping (the os with the ext2 fs) is
_far_ worse than _any_ application-side swapping.
