+ * The observedSet abstraction is a perf optimization which reduces the total |

+ * groups of Observers will have some object dependencies in common and this |
+ * observed set ensures that each object in the transitive closure of |
+ * dependencies is only observed once. The observedSet acts as a write barrier |
+ * such that whenever any change comes through, all Observers are checked for |
+ * changed values. |
+ * |
+ * Note that this optimization is explicitly moving work from setup-time to |
+ * change-time. |
+ * |
+ * TODO(rafaelw): Implement "garbage collection". In order to move work off |
+ * the critical path, when Observers are closed, their observed objects are |
+ * not Object.unobserve(d). As a result, it's possible that if the observedSet |
+ * is kept open, but some Observers have been closed, it could cause "leaks" |
+ * (prevent otherwise collectable objects from being collected). At some |
+ * point, we should implement incremental "gc" which keeps a list of |
+ * observedSets which may need clean-up and does small amounts of cleanup on a |
+ * timeout until all is clean. |
