> Currently, if HandleHttpResponse cannot write to the OutputStream, it catches 
> the general Exception and routes to 'failure' without removing the entry from 
> the map. If clients often timeout, though, we will fail to write to the 
> OutputStreams and then leave the entry in the map, preventing new connections.
> If a ProcessException is caught when calling ProcessSession.exportTo, we 
> should remove the entry from the map before routing to failure.
