I don't think that Lib/test/ is in sys.path. It's more subtle than
test. When you run "./python -m test test_bisect",
Lib/test/regrtest.py imports "test.test_bisect", and so test_bisect is
imported with __package__=['test'].

With test_bisect.__package__=['test'], "import bisect" in
Lib/test/test_bisect.py imports Lib/test/bisect.py.

The question is more when Lib/multiprocessing/heap.py got
Lib/test/bisect.py instead of Lib/bisect.py. I didn't dig into this
issue. The Python 2 import machinery blows my mind :-)
