'done' is just a boolean for the child thread to indicate it has finished.
The main thread keeps a dictionary of references to the child threads so
the app can send then 'abort' messages via their input Queues. When a child
thread sets 'done' to True, the main thread deletes its reference from the
dictionary.

Periodic polling triggered by a timer in the X-app main loop was the only
way I could think of checking for feedback from the child threads, not very
neat though...

Thanks to everyone for their input!
