Drat. I was hoping to arrive at a number similar to top's
Free column. Right now the vm stat from sysctl is about 25% of what
top's reporting (256MB physical). At the same time... the free pages
may be a good value for me to toss around given that I'm also
including the load and some statistics of the host's past.

Phys mem + swap, which I think I can calc pretty easily now
that I have swap. -sc
