Mark Johnston 9c770a27ce Simplify vm_pageout_init_domain() and add a "big picture" comment. 
Stop subtracting 1024/200 from vmd_page_count/200.  I cannot see how
such precise accounting can make a difference on modern systems.

Add some explanation of what the page daemon does and how it handles
memory shortages.
