PINRemoteImageWeakTask memory leak

[rounak]

We're seeing some PINRemoteImageWeakTask leaks in the memory graph debugger. Looking at the PINRemoteImage code, we store this weak task using [NSURLProtocol setProperty: forKey: inRequest:] method. But we never seem to be removing this task through the corresponding removePropertyForKey method call.

Is this expected? Or is the leak due to some other issue?

Thanks!
