Interesting bug.  I think the problem is that priorities should not go
below 1.  I don't want to try it myself, though, just right now, if it's
going to crash my image :)

Usually people choose a priority using the named priorities in Process. 
For instance, you can do:

	process priority: Processor userBackgroundPriority

By the way, you might want to put a "Processor active yield" inside your
busy loop.  Squeak processes are only interrupted if:

	1. They suspend or yield
	2. A higher-priority process becomes runnable

Thus if you busy-loop without a yield, you can lock your system up....
