It really shouldn't do that :)

It looks like that may well be what happened - it seems MFS will, over
time, grow to use up it's full size in swap space, even with activity
on just small files such that it really should never need to touch
more than a very few of it's pages. I'd consider this a bug.

Adam asked me to build a kernel with DDB, I'm doing that now, with a
smaller MFS.
