// = TITLE
// Defines a factory that creates new <ACE_Stream>s actively.
//
// = DESCRIPTION
// The <ACE_SOCK_Connector> doesn't have a socket of its own,
// i.e., it simply "borrows" the one from the ACE_SOCK_Stream
// that's being connected. The reason for this is that the
// underlying socket API doesn't use a "factory" socket to connect
// "data-mode" sockets. Therefore, there's no need to inherit
// <ACE_SOCK_Connector> from <ACE_SOCK>. A nice side-effect of
// this is that <ACE_SOCK_Connector>'s do not store state so they
// can be used reentrantly in multi-threaded programs.
