When a tag is reserved and a message is received
with such a tag then one of these is generated
and added to the queue of notification replies.
Multiple of these will be made and enqueued even
if they have the same tag (duplicates allowed).
This facilitates a notification system if one
wants to use tristanable for that purpose (this
is because notifications _just happen_ and have
no prior request)
