BlockContext>>forkAt: returns a Process, which responds to terminate.

so hang on to its return value:

	myProcess _ [ ... ] forkAt: Processor userSchedulingPriority.

and then later:

	myProcess terminate.

However, if the call to contents: will change the UI, and you're
doing this in Morphic, it would be better to do this
inside a step method. Or if you're in 2.9, you can do this:

progress
        myProcess _ [[foo getPercentage < 1]
                whileTrue: [Delay forMilliseconds: 300.
			WorldState addDeferredUIMessage: [
                        	progress value
                               		contents: ((foo getPercentage min: 1.0)
                                                 max: 0.0)]]]
                forkAt: Processor userSchedulingPriority

You'd still call terminate, of course, but this keeps you from running
into problems in Morphic.
