I was recently reminded of a "fun" edge case for PEP 499: "python -m site", which reruns a module that gets implicitly imported at startup (so "site" is already in sys.modules by the time __main__ runs). That said, the way that currently works (re-running sitecustomize and usercustomize) isn't particularly wonderful, so proposing changing it would be reasonable.
