Memory Leak when Engine.enableSleeping == true

[411411qq]

I set Engine.enableSleeping == true, there is some staic objects in the stage. The staic objects will be sleeping in a while. When a dynamic object collide with a staic object, a new Pair will be added to Engine.pairs.list. This new Pair will never be removed, because one object in this pair is sleeping, even one object is removed.
May I do something wrong? And now I know my English is terrible!

Could you try this alpha build from PR #1079 and let me know if that solves the issue? Otherwise if you're able to share a minimal example that would help!
