Having trouble accessing the Interrupt message when execution is halted. I am assuming that the

message does not lie in the "outputs" field of the cell's JSON object. Using a timeout work-around for
|

test with an infinite loop. We know the interrupt function is working if this test passes.
|

Hope this is a good start.
