> The "processRequest(Request request)" function in FinalRequestProcessor.java
> synchronizes around `outstandingChanges` for all requests now. However, this
> synchronization is unnecessary for read requests, and skipping such
> synchronization for reads can improve the overall throughput of the request
> processor pipeline.
