Not on my system it isn't!
It's true that _sre does get imported whenever I start Python, but
that is not because it gets imported by os. There is an import of re
in posixpath (imported by os), but that is inside the function
expandvars which is not called during import.
In my case site.py imports distutils.util because Python decides it is
called from the build directory.
