Title: This patch will prevent some random memory leaking.

The internal closedA object was leaking memory while being totally useless.

It had issues with its size, at random times socket.io stopped removing keys from it,
I found that (Object.keys(closedA).length) was more than 350,000 after running for 10 hours.
