In a workspace [LicheeRV Dock]:

  [1000 milliseconds asDelay wait] valueWithin: 100 milliSeconds 
onTimeout: [] ]
    durationToRun.
   -> 0:00:00:00:102   [102 milliseconds]

  [ [ [5 seconds asDelay wait] valueWithin:100 milliseconds onTimeout: [] 
]
    valueWithIn: 500 milliseconds onTimeOut: [] ] durationToRun.
   -> 0:00:00:00:104   [104 milliseconds]

The preemptions can only happen during #durationToRun, right?  Between 
getting the start time, running the block, and getting the end time.

This is why running the tests uninterruptedly (e.g. Cmd-t in a browser) 
pass and running in background fails.

I think that giving extra time for #durationToRun in background is 
testing the wrong thing.
