Not a stupid question at all. AFAIK, there is no way at the FOP level to
force more swapping than occurs now. There might be things you can do at the
OS level to increase the amount of virtual memory available.

As for "why", the short answer is that it is a non-trivial task to implement
this intelligently. However, it is part of what is being addressed in the
redesign:

I do not know whether XEP swaps.

Short term, that is the right general solution (there isn't a good way of
knowing whether you need 2GB or 200GB). Long term, it might make more sense
to contribute developers or money to FOP development to get the redesign
work done. We have a bunch of talented developers already working on the
project that would love to work on it full-time.
