[issue9915] speeding up sorting with a key

[Terry J. Reedy]

Does this help any?
>>> import random
>>> from timeit import timeit
>>> testlist = list(range(100000))
>>> random.shuffle(testlist)
>>> timeit('t=list(testlist); t.sort()',
    'from __main__ import testlist', number=1)
0.1467957519740679

I just learned the import trick from the tracker issue suggesting that it be made more prominent.
