> Hi, 
> I have tested the VFS functionality with 500 proxies and each proxy pointed to different
500 folders. Then send around 300 concurrent HTTP request to each proxy. With the time i was
able to notice memory growth and Synapse get Memory leak.
> Therefore, i run the 300 concurrent HTTP request again the Synapse and killed client
in the middle. I was able to clearly observe in Jconsole, memory was not released even when
i try to perform GC manually.
> To reproduce this, I have attached the python scripts that i have used to create Directories,
Proxies and Requests.
