Alternative.

Instead of deleting qobjects

emit c->connectionDied();

Clients then call destroy() on whatever objects.
They can then delete the QObjects whenever they were going to.

Yeah that should work as well. Though of course the documentation of ConnectionThread says it's not emitted if created from application, but we can fix that ;-)

It might mean we leak a few resources, but as we are shutting down anyway...

RE: D6727

That would basically allow us to abandon D6571 and would also solve the issues we see with the kwayland-integration plugin which can crash applications on exit.

I'd like to see this patch merged (but with the emit connectionDied)
It might work without, but it still leaves a window where someone calling foo->destroy() would crash.
