 // Number of times to repost a Quit task so that the MessageLoop finishes up
 // pending tasks and tasks posted by those pending tasks without risking the
 // potential hang behavior of MessageLoop::QuitWhenIdle.
 // The criteria for choosing this number: it should be high enough to make the
 // quit act like QuitWhenIdle, while taking into account that any page which is
 // animating may be rendering another frame for each quit deferral. For an
 // animating page, the potential delay to quitting the RunLoop would be
 // kNumQuitDeferrals * frame_render_time. Some perf tests run slow, such as
 // 200ms/frame.
