Now that I've actually had a chance to boot the kernel with the patch
applied I'm sorry to say but the load average isn't decaying as fast as it
ought to, at the very least. My machine's been idle for the last ten minutes
but the one minute average is still at 0.89 and shooting up to 1.5, the 5
min average is 0.9, and the 15 min average is .68 and climbing. Even as I'm
writing this the averages are continuing to drop, but *very* slowly.
Glacially, almost. The one minute average is continuing to randomly spike
high for no reason I can tell as well.

I'll let you guys know if this actually bottoms out at some point.
