"Failure during realize" is one of those cases I don't think we
handle very well. I'd like to see a view by one of our QOM experts
on what the best way to handle this is -- should one do the
cleanup in realize itself, or in instance_finalize? Do the
sub-objects that are being initialized and realized need to
be manually cleaned up in the realize-is-failing case, or is
that part automatic?

Which is to say that maybe this patch is the best way to do this,
but it would be nice to be sure about that...
