shallow size (of all instances)?

[koda, 2014/06/20 18:37:03]

I made a "current instances" section instead. See attached screenshot.

+            <div class="memberValue">
+              {{ cls.newSpace.current.bytes + cls.oldSpace.current.bytes }}

I think this might double count. I'm not sure the correct solution.

[koda, 2014/06/20 18:37:04]

I think that's true, and that the correct solution is for us to track promotions
in the allocation stats. In any case, this is not the place to fix it, i.e.,
this expression *should* give a meaningful number.

+            </div>

See above.

+              <eval-link callback="{{ retainedSize }}"></eval-link>
