thanks,

I already patched my script.
Now it kills pid, then if it fails, gets all named out of jail (J 
flag) and kill these.

The bug report was just so you are aware of this and can take 
corrective action for next release ;-)

And between you & me, this bug is nothing comparing to the other one 
I submitted months ago about IDE driver bug.

Thanks!!
