Interesting. I stand corrected - the executionContexts is documented 
after all. It *is* a bit out of date, though, as it doesn't reflect the 
additional parameter(s) for behavior objects. The additional parameter 
was added in a way that cleverly maintains backward compatibility, 
although if you need to trace your way through behaviors you need to 
take it into account.
