Comment (by ryandesign):

 The old waterfall view was eliminated. A new view called waterfall was
 added that behaves differently and shows less information. When all
 builders were busy, the waterfall view caused Safari to use 100% CPU and
 become unresponsive until the builds finished, rendering it useless for
 being able to see what's going on. In addition, the introduction of the
 virtual builders brings new complications; it now becomes difficult to see
 what a particular builder is doing.
