INT 15 - DESQview v2.26+ - "PROCESSMEM" - GET TASK MEMORY STATUS
        AX = DE22h
        DX = segment of task handle
Return: DX = total amount of memory in paragraphs
        BX = amount of system memory in paragraphs
        CX = largest block of system memory available in paragraphs
        AX = flags
            bit 0: system memory resides in shared memory
                1: process's memory is swapped out
                2: process's system memory is swapped out
Notes:  if the task handle is a child task, the returned values will be for the
          process containing the task, rather than the task itself
        if the process's system memory is swapped out, BX,CX,DX remain
          unchanged, because the memory usage cannot be determined
