I've done some more code inspection and I think my fix is ok.
I'll make the change to my code base and I'll let you know if I have any problems with it.
I've submitted bug #1067 for this.

It certainly *looks* OK to me, but I share the same concerns as you
(I've never really got that far inside the driver before). Anyone else
care to comment?
