Mike / Nathan,

I think I have it.  Thanks for your efforts.  Especially your Mike.

Putting the exec statement inside my timeout logic allows me to echo a failure 
message, then disable output and start killing things.

I have only tested in my test script, but I will be trying it in my 068 script

 >>  Anyhow, good luck.
