 // connections between applications are established. Once Connect() is called,

 // passed to another thread without calling Clone().
 // An instance of this class is created internally by ShellConnection for use
 // on the thread ShellConnection is instantiated on, and this interface is
 // wrapped by the Shell interface.
 // To use this interface on other threads, call Shell::CloneConnector() and
 // pass the result to another thread. To pass to subsequent threads, call
 // Clone() on instances of this object.
 // While instances of this object are owned by the caller, the underlying
 // connection with the shell is bound to the lifetime of the instance that
 // created it, i.e. when the application is terminated the Connector pipe is
 // closed.
