I got two questions after scanning the patch:

(1) For a node with 50 loops and another one 50+10^3 loops, the first 
one will be measured 50 times and the second one will be measured 50+10 
times? I am not sure if this is rational.

(2) Will this patch instruct multinode without interval? This is because 
we always use ntuples=0 for multinode, so the tuplecount will not 

Maybe another way is to measure the cost of timing, then substruct it 
from the result - but this is a hand-waiving only so far ...
