> Currently the synchronized messaging (accessed concurrently via RPC) is done 
> with a single mutex object. See org.apache.hama.bsp.message.SynchronizedQueue.
> This can be improved for memory queue by adding the ConcurrentLinkedQueue 
> from Java since it has higher throughput. 
> Needless to say, we should add some custom synchronized version of a queue, 
> maybe through a factory class in the normal version.
