and people say this revert patch doesn't seem to make the issue go away
fully.  Thorsten has created another kernel with the other patch applied
for testing.

At least I think that is the latest status from the bug.  Hopefully the
commenters will chime in.

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.
