In different ways, but basically - yes.
Sometimes appear in Xorg.0.log messages like:
"[mi] EQ overflowing. The server is probably stuck in an infinite loop."
When I run a lot of programs is beginning to actively use swap,
although i have 4G RAM on my system and if use 4BSD or FBFS this does
not happen...

cc1: PRI 74-86 (4 processes)
X: PRI 20-74 (mainly 74 at high load CPU) WCPU: 0.98%-6.98%

ps ax|grep X
 2786  -  S     3:31,13 /usr/local/bin/X :0 -br -verbose
-auth /var/run/gdm/auth-for-gdm-cqiXfH/database -nolisten tcp (Xorg)

I use script

while [ 1 -lt 2 ]
#ps -p 2786 -uo pri >> pri_test.log
ps -p 2786 -o pri >> pri_test.log
sleep 1

log file pri_test.log as an attachment...
