We keep running into renameFile/deleteFile errors on Windows, the problem being
that Windows normally does not allow you to delete or move over an open file.

As I understand it, the current plan on darcs-users is to fiddle with the way we
open files so that get POSIX-style deletion semantics.

Alas, this is not enough... even if we say to Windows "you should
really allow us to delete the file while it's opened", it won't still
let us delete the directory where the file has been delete, until it
is closed.

I fear that our "move the file somewhere else, then delete it" (not
very clean, but it works) will be the final solution.

It doesn't look like this is still a problem or else the CI would 
produce lots of failures on Windows.
