One option would be to put a thread safe queue of delegates in the main thread.
Then the slot code just stuffs an action into it. Then the main thread, at
some point, run everything in the queue:
not to perdy but it would get the job done for some cases. What would be
niceer would be some sort of interupt, but I don't known how to do that.
