Patch fixes problem for me.
Looks like XFCE is hitting an extremely slow path in glamor, but it does finish
eventually for me.
Probably file a bug against glamor.
Just in case. I gathered sysprof stats for this case, attached as
xfce-logout-hang.prof.

FWIW, I find data from perf or sysprof much more useful than oprofile.
But the CPU might not be the bottleneck for this anyway, it's generally
very hard to beat shadowfb across the board.
In case you decide to look into it I attached 2 sysprof screenshots for
slowest tests: gtkdrawingarea-lines and gtkdrawingarea-text. I am
attaching screenshots because AFAICU real profiles useless without my
binaries.
I also hit screen corruption while profiling, reproducible by following
scenario:
- open sysprog with some non short data, make sure "descendants
treeview" have scrollbar
- start to scroll "descendants" up and down, screen will corrupt.
The "glamoregl" module needs to be pre-loaded (along with "dri2") from
Section "Module". glamor ships a xorg.conf.d snippet for this. Current
xf86-video-ati Git catches this more gracefully.
Works fine this way. Thank you again. I'd like to say I made attempt to
exclude incorrect config by trying with config created by "X -configure".
