Mind to share the flaky error happening sometimes (when the race condition happens or like)?

I cannot reproduce it on my machine.

[am-kantox]

Mix.shell.info/1 makes it fancier, see this for an inspiration.

Suggested change

	use GenServer
	use GenServer, restart: :transient, shutdown: 10_000

Default for :restart is :permanent and I doubt restarting makes any sense here.

[sovetnik]

Looks like this change fixed both tests.
UPD: it wasn't .

[am-kantox]

Task.Supervisor would probably help to make sure all tasks are finished normally.

I cannot believe formatter did not say anything here.

[sovetnik]

But it did not.Maybe sigil ~s allows this kind of format?

Captured failing test on CI!

It seems some timers fix the issue.
