# distutils, setuptools, pip are buggy and allow target packages affect
# their execution environment. For example, if distribution they install
# has re.py, they will import that instead of system re. So, we need
# to remove current dir from sys.path, but that appear to be quite uneasy
# with CPython, so we hook __import__ and exterminate it persistently.
