As Tim noted, this is wrong, you want this in an event-handling
function, not in your chain function. However, once you've moved it
there, you ALSO need to ref the event before forwarding it to each pad,
something like (pseudocode follows);
 foreach pad:
   ref(event)
   forward(event)
 unref(event)
