I think, that is a misconception within bzip2. The alternative would be: - decompress one chunk, and write it to the stdout while the next block is already being decompressed. - compress a chunk, while reading the next one from stdin That would eat up at least twice the memory as it does now. And after i searched portage, i found "pbzip2" - what about that? It may solve your problems ;-)
