John Fremlin's swap patch

Hi John, I haven't had a chance to test your patch yet, but I will be
sure to try it when I get the chance.

Your analysis of the problems with the current use of swap_cnt seems
accurate - though i don't know much about cache miss speeds and such.  I
guess the problem won't fully be solved until the swapping routine is
based on pages instead of processes, and can scan pages on the inactive
list only.
