I've been running this for a day and a half now, and a few hundred megs
of memory is now missing:

# free
             total       used       free     shared    buffers     cached
Mem:       2055648    2001884      53764          0     259024     868484
-/+ buffers/cache:     874376    1181272
Swap:      1028152         56    1028096

I've put the output from the sorting program up at
	http://untroubled.org/misc/page_owner_sorted

Is this useful information yet, or is there still too much in cached
pages to really identify the source?
