knowing the participant can be costly. We often see timeouts regarding
who is subscribed/notified. The subscriptions can change while mail is
queued. Bugs can be made private while mail is queued. Answers solved
this differently. The notification chooses one or more rules (asker,
subscriber, contact) that are queued as jobs. The actual recipients are
determined out of proc at the moment the email is sent. A user who
changes an email address or is deactivated is handled properly.
