I knew about the filesystem restriction, but not the windows restriction.

We didn't consider the filesystem restriction to be a big deal. Since the 
workspace is created and maintained by Stellation, it shouldn't ever
be crossing filesystems. So moving things around within the workspace
should never cause a problem.

Windows is a different situation apparently.

One solution would be to replace the File.rename with a copy to
the new location, and delete from the old.

Why did rename bite you in normalize?
