Thank you for the detailed explanation!

I, for one, wasn't aware of that because I know next to nothing about 
the internas of the X server. Counting the number of comments on that 
bug, I guess I wasn't the only one though. :-)

Is there an easy way to generate traces like that for a new bug report, 
in case a EQ overflow should strike again?

Anyhow I haven't had one single crash like that since I upgraded to F11 
beta. I'm looking forward for Leonidas!
