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.
