v2.10.2 every test suite starts with `:killed` GenServer

[jswanner]

With the only thing changing in an application's codebase being upgrading from 2.10.1 to 2.10.2, every run of the test suite starts with:

15:15:25.084 [error] GenServer #PID<0.625.0> terminating
** (stop) killed
Last message: {:EXIT, #PID<0.624.0>, :killed}

I've been trying to create a livebook to provide a minimal reproduction of the problem but thus far have been failing. If such a reproduction example is needed then I'll be happy to continue to try to create one.

Thanks!

I could not reproduce it any of my two projects, so I'd appreciate an example!

Please disregard... I tracked it down to a weirdness in the application: as part of its startup process it spun up and killed an Ecto repo, but it wasn't using Repo.stop/1. I've reworked the app startup to no longer need any of that anyway.

Sorry for the distraction. Thanks for the amazing library!
