[xmonad] resource leak?

Has anyone seen signs of a resource leak in xmonad recently? I got a problem where programs were dying with a message that I forgot to record before restarting, and am wondering whether we might have recently introduced some sort of a resource leak into xmonad? Alas, I'm at a conference and won't be able to be in decent contact this week. -- David Roundy http://www.darcs.net
