Okay, will do. Is there an idiomatic "short delay" (e.g. 50ms) or just make something up?
Use the largest you can that gives you the needed accuracy. Polling 20 times per second is not that much but might still be overkill.
If you can estimate the time remaining then you could even use an adaptive delay. E.g. wait 90% of the remaining time:
cd play. [ [ (remaining := endTime - cd position) > 0 ] whileTrue: [ (Delay forSeconds: remaining * 0.9) wait ]. cd pause ] fork.
That's assuming "position" is in seconds, of course.
