Say you have a bunch of listener tasks and a few connection tasks running, and at the root of it all is something waiting for some kind of termination event (like SIG{TERM,INT}).
Once the termination condition has been fulfilled, what methods are typically used to cause a clean shutdown of all tasks? (Assuming that some tasks, in particular the listeners, may .await for a long time).
I found stream-cancel, which looks promising -- but I'm wondering what other methods there are in use out in the wild.
