> In StagePage.scala, we round *down* to the nearest percent when computing the proportion of a task's time spend in each phase of execution.  Scheduler delay is computed by taking 100 - sum(all other proportions), which means that a few extra percent may go into the scheduler delay.  As a result, scheduler delay can appear larger in the visualization than it actually is.
