No, chunked output buffering doesn't assure you that the chunks will be
exactly at the size you ask for. The output handler will be invoked when
there's at least 64 bytes in the buffer, but if there are more - it will be
fed all of the bytes. In your case, since you're generating 10K chunks
each time, the buffer fills with a huge chunk on one output statement, so
the output handler will be fed all of it at once.
