Yeah, well spotted!
I have pushed a new version of maemo-optify to gitorious that patches
maintainer scripts to do "late optification" for stuff that dpkg didn't
do.
It's not very well tested yet, of course, so please dig in!

Yes. It is unfortunately not possible to replace a directory with
something else atomically. I think the best we can do is to move away
the old directory and put a symlink in its place with two syscalls and
hope that nothing happens in between. The old directory can then be
removed afterwards.
