I don't think there's need to polish this fragment. The "Simplified MI testing"
patch of mine is almost approved, and introduces automatic stepping to the right
line in source.

Ah, and I think I'd need to modify that patch so that if you stop on
the wrong line we error out, and don't wait for timeout -- I think the 
current version of my patch has exactly this problem that Dan pointed out
earlier in this thread.
