Change 15938
-Fixed hang on build error on Windows
-Fixed at least one case where projects could fail to finish compiling with the "this is very bad and should never happen" error, but I don't think they're all fixed.
-Fixed InterruptReturnCode on Windows, which has apparently different now after changes to the way keyboard interrupts are handled by csbuild
