There was a problem hiding this comment.
It strikes me that addTo is now only making a negative contribution toward understanding the code -- mostly because the "...if it's not already there" comment is now wrong. I don't see why the handful of uses of addTo shouldn't just be replaced with, e.g.:
pendingTasksForExecutor.getOrElseUpdate(e.executorId, new ArrayBuffer) += index
