Though there is a nice "feature" of win32 and NamedTemporaryFile, in
that the file is opened exclusively by the single file handle you have
right now.

Put another way, no other process can open the named file, *nor* can the
current process open it a second time.

So I don't have any good idea what the "Named" portion is useful for on
Win32, since it can't be used to actually *do* anything with the file.

Note that this differs from the Linux usage, which is why we ran into
some small problems with the btree overflow code on Windows, as it
expected the current process could re-open the named file...

So it exists, but it is pretty much useless, which is probably why we
didn't use it.
