I personally think panics are preferable to deadlocks.  At least with a
panic, it's obvious that something went wrong, and you have a fighting
chance of finding out why.  Having a computer freeze for no apparent
reason is extremely frustrating - especially if it does so gradually.

If necessary, we can always set the console background to blue and/or
call it a "guru meditation message" :-)
