However, there was a second portion,
421d99193537a6522aac2148286f08792167d5fd, which was then reverted at
49eaaa1a6c950e7a92c4386c199b8ec950f840b9.
The fact that it doesn't happen on a single processor makes me believe
it's still a problem with the quicklists not getting freed properly. It
would be nice if someone could go in with system tap or just plain
"gdb vmlinux /proc/kcore" and verify if there is a large number of pages
queued up on the quicklists on some of the CPUs, while at least one of
them is zero.
(It would be nice to have quicklist statistics exported somewhere, too.)
