send slow task to worker thr then back to EDT, briefly

How do you thread a long-running operation (a "tortoise") that needs to update the GUI? Putting it on the EDT will block all screen
updates and user interactions until the tortoise finishes.

P930 [[Pro WPF in c#]] confirmed my belief that in wpf (as in swing),

1) the task should first be dispatched (from EDT or another thread) to a worker thread, which is designed for tortoises, and
2) any resulting update to GUI is then sent back, from the worker thread, to the EDT, which is the only thread permitted to update
the screen.
