ok, unfortunately i now am facing an issue that i can not reproduce manually. i
suspect that is because of a difference between the test server (started in
withServerDo:) and my actual server.

i could probably set up a clean image and retry it there.
how can i avoid that and run a clean server instance manually in my dev image?

well, i am glad they time out, otherwise i believe the image would be locked up.
the timeout should be paused though while the debugger is running.

so the problem is really that the test would need to run in a separate thread
so as to not block the UI? but to do this, the whole test-running framework
would have to be changed, and it's not something i can do in the test code?

what about a hack to instead make a shorter timeout? let the test fail
immediately, then the UI can bring up the debugger, i can inspect the issue,
fix it and rerun the test?

greetings, martin.
