this is a good idea, but the code in KickerSettings is autogenerated
(KConfigXT) and due to that uses KStaticDeleter. not much i can do about that
without changing (or adding to) the semantics of KConfigXT at this point.

it's not about reclaiming memory, it is running dtor's of objects including
those in the QObject parent/child tree. there may be some classes there that:
have no children ever, guaranteed
need to do nothing in the dtor ever, guaranteed
due to this not being true in many cases, it caused problems in previous
releases.
what i could do is move away from using KStaticDeleters in places like
ExtensionManager ... =/ instead, they'd all have to be destroyed in
Kicker::~Kicker() ... this couples things tighter than i'd really like in
that one place but that may be the only solution =(
