With zero-copy IOCP your buffer *is* the TCP transmit or receive buffer.
 When you have a call outstanding then you could consider the buffer full,
when you have no call then it is empty.

General consensus is one outstanding transmit and one or more receiver
buffers should be waiting.  So you have to decide how this fits into the 0MQ
scheme of handling things.
