Other than: it did not occur to me, no, there is no reason for not using
debugobjects there. :-)

As long as we can tag the object as
- initialized
- active
- inactive

And dump a nice fat warning when the object is activated twice, that
should suffice. Now time is a bit short on my side, but I'll keep in
mind to respin a version on top of debugobjects soon.

Thanks,

Mathieu
