That would be overkill, as lmalloc arranges for Lisp alignment, which Jansson
does not need. We could define new functions (smalloc and srealloc, say), that
act like malloc and realloc except they return NULL for requests larger than
PTRDIFF_MAX. Right now, I expect only the JSON code needs this sort of thing so
we could put the new functions in json.c. If other code needs it later we could
move these new functions to alloc.c.

Yes, that sounds reasonable.
