Well, fork-based solutions mean you have to do inter-thread communication
at some point.  That communication can easily get tricky, so I try to avoid it.
I have also had to look at a number of Squeak images that have haywire background
threads, and a number of Squeak projects that mostly work but then pop up
debugger windows at seemingly random times.  Neither of these happen
with a sequential solution such as polling from #step.
