In certain situations, a network message is written during the writing of another message (e.g., a console message being echoed to a logged in client during the composing of a player fix message).
Now ongoing writers are pushed onto a stack automatically so that the earlier message can be resumed once the new message is done.
Messages are consequently no longer composed directly in the netbuffer, but rather in each Writer instance's own dynamic buffer.
