Subject: [PATCH] Improve scheduler delay tooltip.
As a result of shivaram's experience debugging long scheduler delay, I think we should improve the tooltip to point people in the right direction if scheduler delay is large.
Author: Kay Ousterhout <kayousterhout@gmail.com>
Closes #1488 from kayousterhout/better_tooltips and squashes the following commits:
22176fd [Kay Ousterhout] Improve scheduler delay tooltip.
