and so on... acording to the comment in arch/ppc/mm/fault.c, this
happens when for some reason the kernel cannot satisfy a paging request.

xfs gets killed when rendering a really big font, X when sending it over
to gimp, and gimp when working with large images....

What reason is there to kill a process for memory reasons? Does a single
process need to fit _entirely_ into RAM, or can part of a process be
swapped out? In all of the above cases, I've always had over 100 megs of
swap free. Or is there a fixed limit on how big a process can get?

It is only self protection of the kernel to run not out of memory.
The last process that want to allocate memory when memory is low gets
killed. Looks like that is not smart enough when swap is still
available.
