Odd!  Not only does it not have that behaviour in ghc-4.0[48], it also
didn't seem to work when I tried coding it that way in C.  Maybe tells
you more about my C skills... ;-)

I'll wait until the stable ghc-5.02, and then try this again, just in
case this has indeed changed significantly recently, rather than it
just being me missing something obvious.
