I'm not experienced in import machinery. Here is preliminary patch which 
implements my idea for particular case.

Performance effect is almost so good as manual caching in a global.

>>> import timeit
>>> def f():
...      import locale
... 
>>> min(timeit.repeat(f, number=100000, repeat=10))
0.09563599999819417

Of course it breaks tests.

> standard import function).

Good idea.
