EventEmitter memory leak - too many listeners
MaxListenersExceededWarning.*Possible.*memory leak
Fixes
- 1.Remove listeners in cleanup: emitter.removeListener() or emitter.off() when done
- 2.If legitimate, increase limit: emitter.setMaxListeners(n) with a comment explaining why
- 3.Check for repeated addEventListener calls in loops without corresponding removal
