A delay of that sort, without adequate warning, will cause panic,
aborted upgrades, and a lot of problems.  Instead, I would recommend
giving maximum publicity, especially on the download pages, to the
fact that the cleaning is recommended prior to starting the upgrade,
but must be allowed several hours to run.  I'd even recommend that
it's run overnight, if that's possible.

Incidentally, from which version of KDE is the cleaner available?
