That suffers from the same problem as a system_reboot command in that
the guest may never start the shutdown. If that's an acceptable
limitation, then we might as well implement it directly in QEMU as
system_reboot so its easily available to everyone. Make 'system_reboot'
take an optional timeout arg (default to 60 seconds) after which it
cancels its plans.

This seems the most reasonable thing to me.  As already mentioned,
system_powerdown already is non-deterministic since the guest could
ignore the ACPI event.

It could also send the guest to sleep or initiate the self destruct sequence. I don't think we should press the power button unless the user explicitly asked us to. This means we'll need a guest agent like Xen.

I believe ACPI supports additional buttons, we can add a new one and designate it as a shutdown button. It will only work with modified guests though.
