[issue24015] timeit should start with 1 loop, not 10

Serhiy Storchaka added the comment: That was implemented in issue28240. $ time ./python -m timeit "import time; time.sleep(1.0)" 1 loop, best of 5: 1 sec per loop real0m6.176s user0m0.160s sys 0m0.004s -- resolution: -> duplicate stage: -> resolved status: open -> closed
