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?
