Since you're proposing to replace TemporaryFile anyway, and your
'os.link()' proposal requires that both the file and the hard link are
on the same 'drive' or 'partition' or whatever, why not create the
temporary file on a temp directory that is close (hopefully a sibling)
of the final destination blob directory, then you can be sure that
'os.link()' will work and will be 'O(1)' without any extra effort.

Is there any reason not to do that?
