> Considering below time sequence:
> 1. "entries.offer" is called during "storeData". 
> 2. page saving thread comes in, and poll the entry. Then "entryMap.remove" is called. Nothing will be removed since entry has not been added to entryMap yet. 
> 3. "entryMap.put" is called during "storeData". 
> The result is that entries in "entryMap" may never be removed, and the entryMap can increase infinitely.
