Hmm, they were just compiled in, i didn't anything to instrument them with
dtrace.
I've just started a pgbench/dtrace run with instrumented probes aset_alloc,
aset_free and aset_realloc which just counts the calls to them during
pgbench, the first run gives me
tps = 1035.045523 (excluding connections establishing)
Ideas?
