Not in the case of the cache I think those are
1) The user may want to specify a file name
1a) in that case, he may or may not want to reuse any existing data
if the protocol is seekable in principle (e.g. http).
2) The user may want to specific a directory to create cache files in
   (xdg I think specifies a per-user cache directory, too).
3) The user might want a temp file to be used, but not the default temp
   path. It would most likely be expected to follow the system rules
   for temp files. After reading up on it, tempnam actually seems to
   respect that (so I was wrong about its behaviour).
   It seems mkstemp does not though.
