Race condition in type cache initializer

[PatrickKursawe]

I get deadlocks in my project parallel test runs if I don't initialize the type cache before starting the tests. The issue is easy to reproduce for me, but unfortunately it is not an open source project. I'll try to strip it down and reproduce, but I'd like to already give you a heads up for the issue.
