How quiet was your machine when you ran the tests? I see behaviour
more in line with what you'd expect:
[mwh at pc150 build]$ ./python ../Lib/timeit.py -s'ags=range(1000)' 'x=ags[:]'
10000 loops, best of 3: 31.6 usec per loop
[mwh at pc150 build]$ ./python ../Lib/timeit.py -s'ags=range(1000)' 'x=ags[:].pop(0)'
10000 loops, best of 3: 39.8 usec per loop
About the use of language: it is impossible to sharpen a
pencil with a blunt axe. It is equally vain to try to do
it with ten blunt axes instead.
