Just as a point of interest, as an application programmer I think it's
the type of thing you want to know about quite loudly.  The only
benchmark style figure on this I've ever seen is in this paper
(forgive the long url) which, if you scroll down to the little graph,
shows OS fixup is about 450 times slower that an aligned access.  That
sucks, and if I didn't realise I'd done it, it would suck even more.

Oh, and I think fixing it up automatically & warning is much more
useful than sending a (by default) terminating signal to the program;
though I'm sure others might disagree.
