I'm guessing this issue is re: Drupal 5, but in Drupal 6 there is an
over-zealous temp file cleanup, it only allows them to stick around

That's only the cleanup of the {files} table.

Temporary files coming from uploads are managed by PHP, and should be automatically removed right at the end of the request (if they have not been moved before that), as described in http://php.net/features.file-upload

Other temporary files generated by Drupal modules have to be managed by Drupal. I guess some modules fail to cleanup correctly.
