Note that it is somewhat wasteful to build a complete copy of the noticeboard definition in private memory when in fact only the pointers must have private versions. A later version of the software should take copies only of the pointers but this requires the pointer space to be allocated separately during the definition phase -- in the current implementation the pointer space is not contiguous; pointers are mixed up with fixed information, shape information and board information.
