Why is it not bissectable? In general, I like to add first tests before I modify code. In the best case the test also reproduces the issue. Having a failing test in the build is better than having a bug. In this case the test is too simple, we need to use multiple threads to reproduce the issue. We can switch the order if you don't like this approach.
