Generally, you can't. The server doesn't know it yet itself. For
example, imagine this:
while (condition)
box.session.push()
end
return;
In this case there can be variable number of pushes.
But you know for sure there will be next packet before the
sequence of packets for this request ends - either CHUNK or OK.
