-// connections between applications are established. Once Connect() is called,
-// this class is bound to the thread the call was made on and it cannot be
-// 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.
