Comment 7 for bug 1234904

We know that synchronous DBus calls are making their way through. But they are handled in the current thread, with no message queueing or the like.

The sort of thing I'm thinking is that Mir has affect the threading model of unity8.

Could whatever Qt worker thread that normally processes the DBus message queue / Qt event queue be saturated / deadlocked / just not exist under Mir? I don't know Qt's internals well enough to know how to test for this.
