My strace shows Firefox looping getting thousands of poll() followed by
"read()-1 EAGAIN (Resource temporarily unavailable)" errors. This is
nothing new - Firefox did the same thing under Ubuntu 8.10 last year.
(Last year I think there were more time syscalls in the mix, and the
looping would occasionally eat 100% of the CPU until I killed Firefox
and restarted it.)
