Does this happen with no X apps running, just a naked X server?  If so 
you have something causing spurious hotplug interrupts.  If not, 
something in your session is querying the server a lot.

I believe gnome attempts to isolate calls to XRRGetScreenResources to 
gnome-settings-daemon for precisely this reason (only one app really 
needs to call it and the rest should query through the session bus).

You really do have a toolchain bug there.
