INT 31H 0008H: Set Segment Limit

                                                    Compatibility: DPMI 0.9+ 
 Expects: AX    0008H
          BX    selector
          CX:DX 32-bit size of the segment -1
 Returns: CF    NC (clear) if successful; else AX = DPMI Error Code
    Info: This changes the limit field of the descriptor in the LDT.

    CX:DX if the requested size is > 1MB, then it must be page-aligned (an
          even multiple of 4096--the low 12-bits of DX must be 0).

    Note: There is no corresponding fn to query the limit.  Use the LSL
          opcode to do so.  If the limit might be larger than 64K, you must
          use the 32-bit version of LSL.
