> Yeah, this is a Watcher, a periodic function that is called to clean =
up or check something. Yes, it=E2=80=99s a very specific pattern. And of =
course, the Watcher belongs to the service. If the service is destroyed, =
the Watcher should also be stopped.

It=E2=80=99s a Async\Interval, but it behaves entirely like a background =
fiber (and it can be implemented using a background fiber as well): what =
I mean is, it can be treated in the same way as a background fiber, =
because it=E2=80=99s an background task that can be spawned by the =
library in any method: if await_all was used during construction but not =
during destruction, it would cause a deadlock (because it would wait for =
an uncontrolled background task when exiting the block, according the =
proposed functionality of wait_all).
