Is the number of VM pages supposed to remain constant during a run of
the operating system?  In other words, if I start out with 739 pages
when the system boots (inital value for vm_page_free_count), am I always
supposed to be guaranteed that the value:

  vm_page_free_count + vm_page_active_count + vm_page_inactive_count +
	vm_page_wire_count

remains constant?  (and equal to the number of initial pages?)

I'm trying to figure out where the VM memory leak is that causes pages
to get lost.
