If we reconcile components higher in the hierarchy they will likely reconcile components lower in the
hierarchy. If we sort by depth then when we reach those components there will be no more pending state or
props and it will no op.
There is a circular dependency between `ReactID`, `ReactMount` and
`ReactInstanceHandles`. Ben and I talked about this today. It seems like the
simplest solution is to consolidate a lot of the code that Ben recently wrote
into `ReactMount`. We can later find ways to trim code out of this module
without causing circular deps.
