Yes, I think we now have a good understanding of why this hangs.
The remaining discussion, in my opinion, is if we should block or not while
handling SequencedEvents. I'd like to see strong arguments on both sides to
get this right. Even though my original position was for not-blocking -for
the reasons already shared-, I acknowledge that a deeper investigation is
needed and will do it as soon as possible.
