I don't think we want that much VM. The purpose of increasing RAM was to avoid
thrashing on programs with big working sets (like some parts of Calpa).
Increasing VM size will allow bigger jobs, but those will begin to thrash
again. I didn't think VM size was the bottleneck, thrashing was. We can, and
eventually (e.g. when I return) increase VM size (is that the same as swap
space? I thought it was, but now I'm not so sure), but I don't think it's your
current bottleneck.
