Summary: Pull Request resolved: https://github.com/facebook/react-native/pull/50997 In some apps, we spend a non-trivial amount of time calling ShadowNode destructors on the UI thread. A simple way to avoid stalling the UI thread is to move the `baseRevision_` instance to a data structure that is cleared on a background thread, so it's tree of ShadowNode shared_ptrs are released (and in most cases destroyed) on the background thread. Rather than using std::thread, this change introduces the LowPriorityExecutor abstraction that should be supplied by host platforms. The implementation of this LowPriorityExecutor for each platform is as follows: - iOS: uses dispatch_async to a low priority dispatch queue - Android: uses a pthread with SCHED_OTHER and priority = 19 Moving the ShadowTreeRevision into a lambda capture and punting the lambda to the LowPriorityExecutor moves the destructor calls of the ShadowNodes to the host platform implementation of the LowPriorityExecutor. This change is also guarded by a feature flag so we can keep an eye out for potential memory leaks. ## Changelog [Internal] Reviewed By: NickGerleman Differential Revision: D73688009 fbshipit-source-id: 6a66da248e6fe5c38375bf026499346e8381e75a
