I was timing some cold-cache operations today and had to not use timeit because I wanted to run some code between statement (flushing caches) that shouldn't be timed as part of statement. It would be nice, similarly to -s, to be able to say -i 'something run between statement repetitions'. That is - we run statement in a tight loop some N times, and then repeat that loop some R times, I'd like to run the -i code between the R repetitions, not inside the inner timing loop (since we run that to get timer resolution).

bah, nevermind - I failed to get that setup is called once per loop regardless - I might consider this a doc issue, or perhaps I was just fuzzy brained.
