Actually, cwsdpmi does not use conventional memory except to load itself
and its internal data structures, unless there is less than a certain
predefined amount of EMS/XMS available.  The main reason for this is
that conventional memory is a major PITA to swap to disk.  There may be
others; Charles would be the best one to ask.  But in general, DPMI
hosts do not let your program touch the low 1 MB of memory.
