Locking Pages
=============

   You can tell the system to associate a particular virtual memory page
with a real page frame and keep it that way -- i.e. cause the page to
be paged in if it isn't already and mark it so it will never be paged
out and consequently will never cause a page fault.  This is called
"locking" a page.

   The functions in this chapter lock and unlock the calling process'
pages.
