Well, in this case let's just leave it the way it is. There is nothing
worse than somebody else (who is not using the interface) screwing up
your callback return ;-)

Well, I just kinda dislike the idea of an array holding onto a bunch of
processes without a way about reflecting about them. At some point this
is going to get us into trouble when somebody wonders why the heck this
process doesn't get garbage collected. It would be better if there were
an explicit reference to it somewhere. So I guess it ain't critical (and
requires some image-side support too).
Cheers,
