This can be done, but it would require rewriting much of what relay
uses to allocate structures and buffers. I've decided with my mentor,
Pekka Enberg, that kmemtrace doesn't need this so much, so this is on
my low priority list. I agree it would be nice, but it probably won't
happen until kmemtrace is done.

The bright side is most of this patch will still be valid if we choose
to implement static buffers. So this _is_ a step in that direction.
