Hi Richard,

interesting case, I didn't think about it. It's not deferring any 2 events 
but these 2 events in this order which creates the overflow.
- step 1, event3 is processed and deferred
- step 2, event4 is processed and deferred
- step3, we just processed event4, do we have a deferred event? Yes, event3, 
try it again.
- step4, event3 is deferred again, do we have more? Yes, event4
etc.

I need to think more about it, this one is hard.

Cheers,
Christophe
