BTW assuming that there is a disk cache with write caching enabled
running, would it intercept such a port write and then allow it after it
flushes its write buffer?

If the above doesn't happen then it would be very dangerous indeed to use

reboot...

Thats why we all love Linux..... it is 100% secure, you can visit any
site, and read any mail with confidence that there is no such thing as a
virus as far as linux is concerned :)
