I surprised how functools make import time slower.
And I find namedtuple makes it slower.

When I replaced

_CacheInfo = namedtuple("CacheInfo", ["hits", "misses", "maxsize", "currsize"])

this line with `_CachedInfo._source`:

(before)
$ ~/local/py37/bin/python3 -m perf timeit -s 'import importlib, functools' -- 'importlib.reload(functools)'
.....................
Median +- std dev: 1.21 ms +- 0.01 ms

(replaced)
$ ~/local/py37/bin/python3 -m perf timeit -s 'import importlib, functools' -- 'importlib.reload(functools)'

Median +- std dev: 615 us +- 12 us
