But this has been haunting us since we upgraded.

Alright. What if we divide tests into two groups for Native build?

@danicheg Unfortunately the problem is likely a bug with MUnit or Scala Native itself. MUnit was hastily upgraded to multithreading.

I wonder – are there some other projects that suffer from the similar issue after upgrading to ScalaNative v5.x? I only see it for Cats for now, but I may not be aware of all the projects around.
