yes it's a good idea: however one thing at a time.  if cole chooses to
do that, he'll definitely he'll need help with it, and it'll
definitely need to be under a new bugreport.

the first goal is to keep it *really* simple for him and to simply add
"some test that happens to loop through a stack of opcodes" just like
the nested div test.

this to be a maximum of around 15 lines of code.

adding the use of pia - although it is a good idea - is well over 80
lines and a much larger task for him.
