jay What makes you believe that there is a memory leak? Each object is created per request and should be GCed after the request is complete.
I ran the code via node-inspector with apache-benchmark to see the problem of memory leak and did not find any issue. Below is the snapshot of the GC from the start and then from the end. Things look ok to me.
