No idea, but I often see similar:  F14 x86_64 laptop (2GB ram), firefox
w/Flash Square.  Just when I really need to use the computer, the load
average goes through the roof (> 8).  The machine starts swapping,
firefox's memory usage grows large (multi-GB), and the machine becomes
*very* unresponsive until whatever it was trying to do finally finishes.
 Sometime I can fix it by logging out and logging in again, other times
I have to reboot.  Right now my load average is around 3.3.  That seems
a bit high for a system not doing very much other than writing an email
(thunderbird) with about 30 different tabs open in firefox not doing
anything, and 4 gnome-terminals open waiting at command prompts.

I too suspect that firefox and audio is at the heart of the problem, but
I can't prove it.
