:Maybe we could optionally call a debug back-end allocator, in place of
:the client-specified one, that allocates whatever additional memory is
:needed (e.g. room for a (partial) call stack).

   I would stick with the basics first.  I don't think anything
   sophisticated is needed, frankly.  The first priority would be in
   detecting that there's a problem in the first place.  Finding the
   original free could be as simple as adding a couple of KTRs.
