Calling it a "state machine" is a little tortuous. It's a single bit
flag: on a REQ socket, ready to send to network, or waiting for
response from network; on a REP socket, ready to receive from network,
or waiting to reply to network.
Which just prevents the caller sending twice, or receiving twice in a row.
