Well, in effect, the answer is yes. It does require a whole set of data
before compression, but to combat this, the data is split into blocks, and
each block is compressed individually from a buffer.

I'm wondering if you would get better compression by treating the whole
stream as 1 block, and then compressing that, or compression in many smaller
blocks. I guess it all depends on the compression used.
