OK, I've done that. As Anna noted, actually this produces too many false
positives anyway.

I think what I hoped is that the annotations would let me tie in to the
existing malloc warnings (which
would allow me to usefully annotate other functions which I know return
allocated memory which
ought to be freed) but in fact it's using a quite different checker which
(for our codebase) is too noisy to
be useful.
