what I imagine is simpler than that;
have the coredumps go to a specific directory on the system and just
watch that directory from some daemon.

Alternative is actually nicer; the new kernel can actually pipe
coredumps to a program, that can just take care of all this from the
start; no audit things needed whatsoever; that'd just be pointless
overhead.
