i dont know anything about stop_delay, but if you specify the
start_delay for the operation
ie. <op name=start interval=0 timeout=60s start_delay=40s/> , and/or
<op name=stop interval=0 timeout=60s start_delay=40s/>
then everything will work as you expect (the 40s is automagically
added to the 60s timeout)

No, you need to specify it for every operation you want to delay the
execution of.
