FWIW, if your application is interactive, I would do that test in a step 
method rather than a background process. I.e.,

	"Start playing and establish the time watcher"

	cd play.
	self startStepping: #watchPlayTime  at: Time millisecondClockValue 
arguments: nil stepTime: 20.

	"is it time to stop playing?"

	cd position > endTime ifTrue:[self stopPlaying].

	"Stop playing. Also stop the watcher."

	cd pause.
	self stopStepping: #watchPlayTime.
