[ASRangeController] We're already on main thread, remove blocks Make data source read-only, clarify what's asynchronous [ASDataController] Clean up some interfaces [ASDataController] A little more cleanup [ASDataController] Cleanup [ASDataController] Restore some changes, exit more often [ASDataController] Use item counts that we already have rather than requerying them [ASDataController] Revert weakifications [ASDataController] Add a mechanism to measure how much work we avoided
