Currently, we are allocating buffer for RPC messages statically. This is not such pain when RPC limits are small. However, if we want ever to increase those limits, we need to allocate buffer dynamically, based on RPC message len (= the first 4 bytes). Therefore we will decrease our mem usage in most cases and still be flexible enough in corner cases.
