Forgive me, it was a late at night comment after drinking too much - I don't
know what I was thinking! However, as a general principle, if the PC was to
pull traffic off the card, switch it (i.e. reorder it) and put it back on,
it would probably take some time to get over the various timeing and
synchronisation issues that this would present.
