I am seeing kswapd0 hogging a cpu right now. I have two rsyncs and an md sync
running and a couple of large memory processes (java and firefox) idle.

I haven't been seeing this happen as often as previously. Before doing a
yum update with an rsync was pretty good at triggering the problem. Now,
not so much.
