Well, Louis doesn't actually _want_ swapping or reclaim on them. He just
wants the system to run well with the remaining 400MB of memory in his
machine.
Which it doesn't. It just OOM's for some reason.
We still haven't seen the oom debug output though, I think. It should talk
about some of the state (it calls "show_mem()", which should call
"show_free_areas()", which should tell a lot about why the heck it
thought it was out of memory.
But maybe Louis posted it and I just missed it.
Anyway, if it's hugepages, then I don't see why Louis even _wants_ to turn
down swappiness. The hugepages won't be swapped out regardless.
