 Perhaps if we use `CreateFile` to open our own `cabal.exe` file and
 specify `FILE_FLAG_DELETE_ON_CLOSE` then hopefully that would actually
 delete the `.exe` file when the process closes (which would be when the
 last handles are closed).

 This relies on the `.exe` file itself being opened by the kernel with
 `FILE_SHARE_DELETE` sharing. This would appear to be the case though since
 it is possible to rename a `.exe` file while the program is running.
