Note that processes that expect to be VM hogs should probably do their
own "swap" allocation with mmap() or some such. What would be nice to
go with that is an extention to malloc & friends so that you could
mmap yourself some fresh VM, and tell malloc to use that as the arena
(or to add it to the existing arena)...
