> For optimal disk performance, it makes most sense to choose our compression
> boundaries based on compressed size, not uncompressed. If our compressors
> could take a target length, and return the number of source bytes they
> managed to fit into that space, this would permit us to lower the number of
> disk accesses per read. [~blambov]: you've dived into LZ4. How tricky do you
> think this might be?
