does this mean X defaults to nice level 0, and then if you renice
Firefox and X by +10, everything is fine? Or is Linus' suspicion, and X
defaults to something like nice -5? (e.g. on Debian type of systems)

but ... i havent seen problems with Firefox and flash myself. My 3 years
old son's favorite kid's site is fully based on flash, and the 833 MHz
laptop is still usable remotely while he browses around on it. It's
Fedora Core 4, and X is not reniced.

but if the X server is not reniced then it would be nice if i could
reproduce the starvation ... which site is the one triggering it? (and
could you check www.egyszervolt.hu, and click around on it, does it
trigger similar starvation problems too?)
