[Cuis-dev] batched updates

[Weslleymberg Lisboa]

Hi, Mark

It seems your method is delaying UI updades. AFAIK our code runs on the 
UI process by default, so long-running computations will block the UI. 
You can see this by evaluating:

1 to: 10 do: [ :n |
	n print.
	(Delay forSeconds: 1) wait. ]

On Windows, my transcript updates but the rest of the UI freezes completly.

To avoid this you can start the long-running method on a new process:

[ 1 to: 10 do: [ :n |
	n print.
	(Delay forSeconds: 1) wait. ]] fork.

If you want to control when to start your computation, you can call 
#newProcess instead of #fork and save the returned process so you can 
call #resume on it later.
