Socket's primitiveOnlySupportsOneSemaphore instance variable sneaked back during the IPv6 integration, let's get rid of it one more time.

  A Socket represents a network connection point. Current sockets are designed to support the TCP/IP and UDP protocols. Sockets are the lowest level of networking object in Squeak and are not normally used directly. SocketStream is a higher level object wrapping a Socket in a stream like protocol.
  
  ProtocolClient and subclasses are in turn wrappers around a SocketStream to provide support for specific network protocols such as POP, NNTP, HTTP, and FTP.!
