That would be nice to have shift-alt-. or some other key combination bring up the emergency evaluator.  (Doesn't VisualWorks support something like this?)

One extra "good thing" you could do in the Emergency Evaluator in these situations might be to start up the CPUWatcher (a.k.a. PigWatcher).  This could be useful if you have a higher-priority-than-UI process running amok, in which case alt-. doesn't help you.  (I assume the shift-alt-. would be detected at a higher level than UI processes.)  You could even have a special keyword (like "revert" currently is) in the emergency evaluator for this.
