Add map transition for observed objects · 625a0e97

adamk@chromium.org authored Jul 13, 2013

This patch enables objects to undergo a single transition when they become observed, avoiding the need to create a new map for every observed objects.

Observed objects which become unobserved does not cause another map transition and unobserved does not clear the observed bit on the map. The unobserved object.
