   // (already true of every protocol built on this framework -
   // TCPSocket::onDataReceived() loops over every complete line already
   // buffered, not just the first one read), and now UIDL (real as of
   // __POP3_UIDL.cpp). Still nothing claiming APOP, STLS, or SASL,
   // since none of those have a real handler behind them.
