Perhaps _go32_dpmi_simulate_int() should abort if SP is not evenly
divisible by four?  It's not clear that you ever want an SP *not*
evenly divisible by four, and that would help catch some uninitialized
SP bugs.  The overhead for this check is insignificant compared to
everything else that happens.
