Fix get_num_ops internal code.

Browse Source 
Previously calling get_num_ops more than once would have ended up with ops
getting double counted, and not calling inbetween completes would have ended up
with ops getting missed. Fix this by moving this to where the work is actually
done, and add tests for double calls to get_num_ops().
