GUI daemon spin in endless loop, holding appviewer.lock when VM died (sometimes)

[marmarek]

It happens only sometimes, but is pretty bad then - all the windows are frozen.
Actually I can reproduce it only using our automated tests, never happened on
real usage.

I had some "all windows freeze" issues some times after boot. Didn't
investigate. Perhaps it was this issue. So I would say this is critical
and very much worth fixing.
