kswapd gone nuts in RH 2.4.9-13 kernel

Just in case anyone is running RH's latest updated kernel,
I just noticed that it's kswapd is running at near MAX CPU usage
on my just-installed RH 7.2 machine.

I'm running about 10Mbps of ethernet traffic on the machine, and
a Java GUI and not much else.

I guess once again I'll be shipping a bleeding-edge hand-built
kernel :P
