Ok, thanks. But the "object" needs to kwow wether the control
was already running or not. I can't check the reference count,
can I? (Ok, I'll probably can associate a value with a prop
bag or something, but I'm searching something 'clean' => maybe
checking if the factory was already running or not?)

Sorry, if I'm missing something obvious here :-)
