If the long-running task is quickly kicking off some network request
and then waiting for the result to arrive at some point in the future,
then you can do all this in the GUI thread (provided you don't stall
the GUI thread while creating the request).

I have actually done this in the past with GTK on Linux.

Still not sure if this is what Lawrence is thinking of however.
