IIRC, on NeXT,  the dock is managed by  the WorkspaceManager.app. It's
not a  separate application.  The WorkspaceManager is  the application
that handle the drag-and-drop of icons. Therefore, it's easy for it to
check if an icon is moved over a dock position.

Personnaly, I don't  see any reason why the dock  should be a separate
application.  (If we  wanted to change the behavior of  the dock or of
GWorkspace,  we  have  the  sources   to  do  it  and  subclass  their
implementation).
