On machines running a kernel about 2 weeks to 1 day old, I've noticed
a lot of sluggish behavior.

Mozilla takes a lot longer to start up, and tends to thrash the disk a
lot more than usual.  Other applications are also seeing less
available memory, or something.

I can't put my finger on any one thing that is broken, just describe
it as "uses swap where it never used swap before" and "even X redraws
slowly now" sort of things.

Am I alone?
