Presumably ones in loops are the nasty ones.  I couldn't see anything
obvious.

I haven't looked for cases where we're disobeying "exit" from shell code
owing to the same logic, but I think the fix there would probably be
different (you may be stuck in a loop in shell code).  This is
completely hypothetical, though.
