What about this case?  Was the comment misleading?

Why counting?  Why not just 'status=0 && continue'?

Note: I have not even begun to audit if one of your returns should not 
have been a "status=0 && continue" instead.

But here you use the simpler paradigm of setting exit_status?  Why that 
complicated and ugly "total" and "success" counting before?
