Thanks for the response, that’s really helpful!
Things really clicked when I realized that tasks run under Task.Supervisor are always linked to that supervisor. Task.Supervisor.async and Task.Supervisor.async_nolink are used to decide whether to link (or not) to the caller of those functions, which should be a GenServer that should probably do something about the messages from the tasks.
Then I also realized that if I want to do any extra bookkeeping after the tasks complete, it has to be done in some GenServer, not in a supervisor.
Once I’m done with my stuff, I’d like to work on a PR to improve the docs for the Task.Supervisor.
