The Issue
We had many tests where the t.Cleanup() was asserting on failure to remove a file or several files on traditional Windows. This happens often on Windows NTFS, which is a bit of a different animal; you can't delete something that might be in use. Due to the eccentricities of Docker and Mutagen running, these types of problems can happen regularly, so it's best just not to check, since we're just cleaning up anyway.
This is only for tests, and only to result in less false-failures on Windows. There is no need to get it in soon for release or anything.
