it used to be solaris (i don't know if this is still the case) would
evict pages to swap even when used + cache << phys memory.
i did quite a bit of performance work on solaris, and found i couldn't
use more than a fraction of available memory. we moved the same
applications to aix and got much better performance with the same amount
of physical memory, as we were memory bound.
