I suspect if this was a problem the zlib people would have added
internal buffering ages ago. I find it hard to believe we're not the
first application to use it this way.
I suppose it wouldn't be the first time a problem like this went
unfixed though. Is the zlib software actively maintained or was your
earlier comment implying it's currently an orphaned codebase?
