1. Unmanage the list first.  Not necessary if you do 2 and 3 below.

2. There is an undocumented function XmListDeleteAllItems(lw); well, it's
undocumented in 1.1 if you still have the 1.0 docs.  It may be there in 1.0.
I don't know.

3. Build your own item list and set it and itemCount with XtSetValues.
