There seems to be a memory leakage in store.js file

Can you tell us more about that?

@small-lovely-cat

when users browses through different topics, the _identityMap seems to be growing rapidly with each restful request. Without a proper cleanup logic, the map will exhaust memory with large js heaps.

Do you have any data to back this up?
