In https://github.com/flutter/engine/pull/3833 the `_flutter.listViews` RPC moved from thread based to lock based synchronization. The thread based synchronization side effect was used by flutter benchmarks in https://github.com/flutter/flutter/blob/master/packages/flutter_tools/lib/src/vmservice.dart#L1223 and https://github.com/flutter/flutter/blob/master/packages/flutter_tools/lib/src/run_hot.dart#L156 to ensure the completeness of the restart/reload and so correct timing. A new RPC `_flutter.flushUIThreadTasks` is introduced to allow the flutter benchmarks to reintroduce thread based synchronization. Related https://github.com/flutter/flutter/issues/11241
