    This case was already broken back when the x86-64 port used to run
    with NMI watchdog on by default, because any IO exception handling
    with interrupts off would trigger the NMI watchdog eventually.

    I remember having to add bandaids to Fusion for this a long time ago.

    Of course ISA drivers might still do it.
