Well this is odd. I just restarted the Windows build bot after taking it offline to do bisections, and now it seems to be green (it was previously showing 126 test failures for most of the day). So I guess we can just forget about these failures, it must have been some configuration issue with the bot or something. Thanks for looking into it for me though, appreciate it, and sorry for the noise!
