Eh, apologies.  This email was an unfinished draft that I had laying
around before the holidays which I intended to discard it but somehow
kept around, and just now I happened to press the wrong key combination
and it ended up being sent instead.  We had some further discussion,
after which I no longer think that there is a problem here, so please
ignore this email.

I'll come back to this patch later this week.
