INT 31H 0701H: Discard Page Contents

                                                    Compatibility: DPMI 0.9+ 
 Expects: AX    0700H
          BX:CX starting linear address of pages to discard
          SI:DI size, in bytes, of region to discard
          ──────────────────────────────────────────────────────────────────
 Returns: CF    NC (clear) if successful; else AX = DPMI Error Code
          ──────────────────────────────────────────────────────────────────
    Info: Discards the entire contents of a specified region of linear
          memory.

          This lets you optimize virtual memory access.  When a memory area
          will not be needed again, discard it.  That way, the DPMI Host
          won't bother swapping it to disk.
