Cured by doing a safe boot and then restarting normally ? Really ? < cue twilight zone music >
Somewhere along the way, Mountain Lion started getting oodles of these errors in the console log… usually every 4 minutes or so. It’s been common enough that there are posts about it on quite a few sites. Surprisingly, the fix really is a simple as a safe boot. Apparently safe boot cleans out some cache files which were causing a problem.
