/**
* Provides a socket that wraps an org.newsclub.net.unix.AFUNIXSocket and delays setting options until the socket is connected. This is
* necessary because the Apache HTTP client attempts to set options prior to connecting the socket, which doesn't work for Unix sockets
* since options are being set on the underlying file descriptor. Until the socket is connected, the file descriptor doesn't exist.
*
* This class also noop's any calls to setReuseAddress, which is called by the Apache client but isn't supported by AFUnixSocket.
