App shutdown takes a long time.

[mori1234]

When I addChild a Spine to a scene and wait for a long time in that scene,
then press a button to exit the app,
calling SkeletonBatch::destroyInstance() takes an extremely long time

• sometimes more than 40 seconds. Is there any solution for this?

when scene change call _eventDispatcher->removeAllEventListeners(),
the EVENT_AFTER_DRAW_RESET_POSITION event gets removed, so SkeletonBatch::reset() is not called, and the cause is that _commandsPool size keeps increasing.

I can't reproduce it

It was my mistake. When changing the scene, I accidentally removed all events, so the EVENT_AFTER_DRAW_RESET_POSITION event was also removed, which caused SkeletonBatch::reset() not to be called, and the _commandsPool size kept increasing, which was the cause.
