I'm not sure that's true: if the buffer is full and the next
lz-decompress-read does not read anything, then the buffer will still be
full and lz-decompress-write-size will return 0.
The specs don't guarantee that lz-decompress-read will always read
something.
But that's the only assumption we are making I believe, and it's fair :)
