Xorg-server 1.9 excessive CPU usage through a 32-bit chroot - bug?

Xorg goes crazy tapping my cpu usage when I compile in a 32-bit chroot.  >60 % of the total CPU is going to Xorg rather than to gcc (running Gnome if that matters).  The htop screenshot below shows X and gdm using it.  I know that if I start gnome from init 3 without gdm the same problem occurs except htop just shows X as the culprit.

X :0

Further, packages fail to build when I run makepkg through X.  If I run it when I'm in init 3 without X at all the very same package successfully builds.  If I leave myself logged into Gnome and open tty1 and enter the chroot there, it builds.

Any thoughts why?  That has to be a bug in Xorg given the conditions I explained above.  Does anyone have an idea as to preventing this?

I entered the 32-bit chroot via: linux32 chroot /opt/arch32 /bin/bash

The package I was attempting to build under X is a kernel if that matters; here is the last bit of the log before the error:
