You should make it clear why the current mechanism is unsatisfactory.
_autorebase is already designed to be run whenever a dll is updated.
Maybe it isn't being run early enough in the postinstall process but,
if that is the case, it probably is a minor change to setup.exe which
doesn't involve lots of new code.
