> calls __dpmi_discard_page_contents to delete one page of address space 

This call does not delete the address space, it just makes the contents
undefined.  You must convert the page to be uncommitted to generate a
fault.  You're on the right track, just using the wrong call.  The call
that would make it read-only can also make it non-existent.
