Comment 21 for bug 309776

I also add a trace of the Xorg process, but is has almost no meaning to me :-(
(althought it seems stange so many calls to clock_gettime and setitimer, consuming almost 25% of the time)

$ sudo strace -v -f -p 5184 -c
Process 5184 attached - interrupt to quit
^CProcess 5184 detached
% time seconds usecs/call calls errors syscall
