maybe it opens a file just to be sure that the name is indeed reserved 
an dnot taken by another process in tne meantime, so os.tmpdir() is 
needed; i wonder, maybe it makse sense to accept an optional argument 
that for the root so that one can generate a tmpdir at a specific 
location i.e. tmpdir("/tmp") or so
