> Result.readFields() used to read from the input stream in 8k chunks to avoid
> OOM issues with direct memory.
> (Reading variable sized chunks into direct memory prevent the JVM from
> reusing the allocated direct memory and direct memory is only collected
> during full GCs)
> This is just to verify protobufs parseFrom type methods do the right thing as
> well so that we do not reintroduce this problem.
