Research direction
The issue describes a memory leak in React Native Debugger after extended use. To investigate, reproduce the leak using the specified versions (0.8.1/0.8.2) and iOS Simulator. Use Chrome DevTools memory profiling to capture heap snapshots and identify retained objects. Focus on the helper process or any components that retain references. Check if any timers or event listeners are not cleaned up. Review the 16 comments for additional clues on reproduction and potential fixes.
