One thing that I was considering was making all binaries effectively
PIC, and placing them at different points in the address space.
An idea probably hated by unix hackers in general, but for small sets of
processes it seemd an interesting way of preserving the cache between
some context switches.
Eg if we only allow a process 512MB of VA space, we can map each new
pmap (sorry, a BSDism although I don't work on that any more either) at
say 4KB + (512 * (i%6)) or something like that. Even with 1GB per proc
you'd have enough room for 3...
Thoughts?
