> In this case the delivery may have a single peer (e.g. inbound), while that peer has multiple peers (eg. outbounds). The current code assumes symmetry (either both have multiple or both have single peers).
> Can result it crash with backtrace when receiving clients unexpectedly disconnect while a large message is being multicast:
