os.path.getmtime could be used in a tight loop, to sync directories with

100000 loops, best of 3: 2.67 usec per loop

100000 loops, best of 3: 2.02 usec per loop
a 25% markup is a lot imo.
I don't think those results are very informative, since
os.path.getmtime() accepts both str and bytes, so it must already have
the str/bytes check.
