i see that file pages are ~60% of the system memory.

what are the vm.{file,anon,exec}{min,max} values?  the default for
file{min,max} are {10,50}, so it should be ejecting at least 10%
of memory really easily to get under filemax.  if those pages are
dirty why aren't they being paged out... (system boot, and pools
are also using about 15% of memory currently..)
