In some limited testing of this patch, I found that:
- It did indeed cause crashes in the input system with the X server that
was in Fedora 14. I think these are known bugs that have been fixed in
newer X servers. (Should we care whether we trigger bugs in older X
servers?)
- With the X server in Fedora 17 it does not cause crashes.
- When I go to
http://ie.microsoft.com/testdrive/Performance/FishIETank/
the X server will max out 3.5 cores and firefox will use the remaining
half core, but judging from looking at the fish and the page's FPS
meter, the performance isn't actually better.
Profiling shows that 50% to 75% of the time is spent in a function in
libgomp.so called something like gomp_wait_for_barrier().
