In this paragraph I was referring to the real underlying OutputStream 
though, not the Deflater (afaict the existing implementation just calls 
through to the underlying stream currently).

The second paragraph is where I talk about the Deflater.  And anyway I 
change my vote from "yes-kinda-no-but-qualified-yes" in favor of the plan B 
patch which I like a lot.
