We've been using action.mindy() in a few places when we need a root user, which creates a new admin user ("mindy") every time. When these user creation requests happen at the same time we occasionally get random failures of our e2e test suite due to database deadlocks.
A simple workaround (hopefully) is to use action.root() instead which uses the pre-existing (per api config) root user instead of creating a new mindy admin user.
