 I tested it on today's STABLE (looks like the patch is against CURRENT, 
 but I managed to apply it to STABLE, there was just some extra spaces in 
 a couple of places). Seems to be working (do you need screens ?). At 
 least I can say - the freeze timeout is now around 5 minutes 
 (unfortunately, I didn't measure the exact amount of time), against one 
 hour before the patch. Hop I will be able to diminish it even more by 
 tuning the kern.cam.da.default_timeout.
 Thanks for the great work.
