The patch that was being worked on at the time wouldn't have come close
to applying to 8.2, because the win32 shmem code got rearranged very
substantially for 8.3. However, AIUI it's the same underlying
technology, so in principle it could be fixed the same way.

If we take seriously the proposition that we're still supporting 8.2
on Windows, we probably ought to do something about that. If we don't,
we need to officially deprecate that version.
