BTW, I have a box with 128MB ram and 512MB swap running 2.4.21-jam1 (it has
the -aa vm). I can't shut it down cleanly, because trying it goes into
endless loop trying to free memory when turning off swap. Nothing but
alt-sysrq-b seems to work.

I don't know if there is a kernel memory leak, since all user level
processes should be killed at that point, right? Unfortunately I didn't have
time to dig deeper, as the box is in (sort of) production.
