[xmonad] Actions on window alerts?

[Joseph Garvin]

Is there a way in xmonad to have actions in response to a window being
alerted (when it blinks in gnome-panel)? I'd like to have a desktop to
toss instant messaging windows onto to disregard them until the person
I'm talking to replies (which causes the window to alert if it
currently doesn't have focus) at which point I'd like it to move to
whatever desktop I happen to be working on so I'll notice it.
