Thanks! Sorry for the wait, I only just got internet in my new house. I'll merge this now but I'd like to write an automated test against this when I have time. Do you have an example of code that causes this kind of data race?

I tried to write a test for it but didn't really managed to have one working. We had the crash on startup of a complex multithread program, with multiple threads probably calling into windows-dll at around the same time.
