There is an easy fix for it, just change one expression in

    ParagraphEditor>>debug:receiver:in:

from this

   [debugger interruptedContext method == aCompiledMethod]
       whileFalse: [debugger send].

to instead

   [debugger interruptedContext method == aCompiledMethod or:[guineaPig 
isTerminated]]
       whileFalse: [debugger send].

The issue is that because the expression has no send the simulation runs 
away and causes a bunch of problems.

BTW, since this thread is about mastering Squeak, if you can explain why 
the runaway simulation suspends the simulator process I will personally 
acknowledge your mastery of Squeak. I couldn't figure out why that 
happens :-)
