Is this the right place to test? Is it correct if a page first is
non-zero and then becomes zero? Perhaps you have to test where you add
a page to a chunk, instead.
Oh, thank you. Huge bug - I need to introduce a "COMPRESS"
message for this page into the protocol just like we already have
for TCP and bypass the current chunk.
I knew I was forgetting about compress - some little angel on my
shoulder was telling me I forgot something but I couldn't remember =)
