Very minor performance hit (at least it should be minor, but I never
measured it).

Yes, it's used by 3 different things:

- tls (runtime, checks if enough free memory is available before
  accepting/creating new connection or even receving packets on an
  existing connection)
- auth - only on init, for sanity checks (and nicer error messages) for
  nc_array_size, nc_array_order, otb_in_flight_no, otn_in_flight_order.
- core.shmmem: it's faster with MALLOC_STATS

We could enable it, but only tls in low memory scenarios will gain from
it.
