Yeah.
Hmm, if it's xmalloc (I'm looking at one patch where it's XCNEWVEC, but
apparently could be XNEWVEC without any loss), then I'm less sure.
XNEWVEC is at least reasonably type-safe, but plain xmalloc less so.
Anyway once unique_ptr is in I'll update all those patches and we can
discuss it more concretely.
