No, this won't do.  However, Sean's suggestion about using testip
should be just fine.

How offensive would it be to make this switchable?  If someone wants
this functionality, they can set an environment variable or
something. 

If I get any decent working code out, I'll let you-all know.
Unfortunately, I'm much more skilled at perl than sh. :-)
