Nested loops with most work happening in pure Python code can cause the 
debugger to be quite a bit slower. The slowdown is proportional to the 
number of Python byte codes that are executed. Some types of Python code 
execute very many by codes and others quite few, because most work is 
done in C code.

Another area that we've seen the debugger to be quite slow is when 
compiling regular expressions with the "re" module.

I do think it's somewhat slower than I would expect, and we'll take a 
look at whether we can optimize this.
