In kernel/monitor-host.c, there are two paths in runGuestLoop()
which call:

  vm_restore_flags()

an if and an else clause.  (well there's one more in the ANAL_CHECK
#if bracketing too)

After the restore, you might check the IOPL value and spew something
via hostprint(), then

  return(1);

to flag an error.  hostprint() will send the error to the kernel
log file.
