Hi, locally this test reproduces the issue on my Windows machine.

I believe our internal testing Windows boxes are too powerful and handle the threading too efficiently to reproduce this error.

I can reproduce locally approx 10% of the time, but after over 100 runs I cannot reproduce as part of our internal testing.

As this is not verifiable in a completely deterministic way, I believe having the test as a stable, passing test is a more appropriate approach instead of selecting this as no-reg hard. 

It adds more test coverage to the code also.
