[development] progress control (like in update.php)?

Borched. Hit 'Send' too soon. This was :

Not really. Progress.js is quite generic, and this is what upload.module
uses.

If you have, say, massive db queries to run (CCK has, for instance, and
it seems node acces rebuild has), and you can't ensure that they won't
hit php timeout limit, and can't defer them to cron tasks, you have to
basically duplicate a large part of the logic in update.php to have it
run in small bits ...

The idea is to provide an API for modules to simply define their
'progressive' / 'batch' / 'whatever' operations without having to
reinvent update.php.
