Shared pages work with DPMI 0.9, but don't work with DPMI 1.0 without extra
calls.  Supporting both environments would be a mess, and you still haven't
solved the "far" issue.  The overhead for a simple program would also 
be way too much, so you would have to support static linking too.  I
personally don't think it's worth the effort under DOS.
