The Windows worker is busy now, so we will see the results of the buildbot [lldb-x86_64-win](https://lab.llvm.org/buildbot/#/builders/211) later. 
But I have reproduced the issue locally. std::this_thread::yield() did not help. I have added the logging to the test and got only 2 threads stopped:
```
        while bkpt.GetHitCount() < 3:
            // hit this point 2 times and then timeout
            process.Continue()
```
I tried to add logging to main.cpp and just adding `#include <stdio>` resolves the issue on Windows.
I don't know why for now.
