I looked at "top", and it seems Firefox (2.0.0.14) is using more CPU than I
think it should, especially considering I haven't used it in the last few
minutes:

top - 12:21:08 up 2 days, 12:11, 16 users, load average: 1.71, 3.28, 2.71
Tasks: 177 total, 3 running, 170 sleeping, 0 stopped, 4 zombie
Cpu(s): 21.2%us, 5.8%sy, 0.0%ni, 71.6%id, 0.2%wa, 0.0%hi, 1.2%si, 0.0%st
Mem: 2076196k total, 1936836k used, 139360k free, 93856k buffers
Swap: 3212988k total, 349196k used, 2863792k free, 760608k cached

That's not unusually high, BTW. This is probably due to some animated GIF
or malformed HTML. Bad scripting is a possibility, but since I disallow
Javascript by default, not as probable as might be expected. How can I tie
it to a particular window? Previously, the method for dealing with similar
situations was "close recently-touched windows until the problem goes away".
That is a rather blunt instrument...
