Size code in GsApp can double-count runtimes
The following discussion from !1351 (merged) should be addressed:
Not your bug since it's not new with this branch, but this logic seems prone to double counting the size of things. Specifically if any of the apps in
priv->relatedhave a runtime or related app that is the same as the main app's
priv->runtimeor the same as one of the already counted apps in
priv->related, it seems like the same size would be counted multiple times. Something to look out for.
