Overview

Provided for forward compatibility in case we need to support different strategies for compressing the IPC message body (like whole-body compression rather than buffer-level) in the future

BUFFER =

Each constituent buffer is first compressed with the indicated compressor, and then written with the uncompressed length in the first 8 bytes as a 64-bit little-endian signed integer followed by the compressed buffer bytes (and then padding as required by the protocol). The uncompressed length may be set to -1 to indicate that the data that follows is not compressed, which can be useful for cases where compression does not yield appreciable savings. Also, empty buffers can optionally be written out as 0-byte compressed buffers, thereby omitting the 8-bytes length header.
