I haven't looked through the code in detail, but one direct comment:
do we really need/want to send this through the stats collector? It
will only ever have one sender - perhaps we should just either store
it in shared memory or store it locally and only send it on demand?
(apologies if it already does the on-demand thing, I only spent about
30 seconds looking for it and noticed it did go through the stats
collector...)
