You can use the control variable to avoid double run as others 
suggested, but I would re-examine the approach. There is no 
requirement that handlers you put in the backscript are the stack 
script. I'd would stick all those needed there into an invisible 
button and leave as stack scripts only those that really need to be 
there. You then insert the script of that button into back.

The shutdownrequest would go either into the backscripts button (if 
you want it to be invoked regardless which stack got it) or into 
stack script (if you want to trap it in that one stack only). In 
either case, you will have only a single instance.
