It doesn't even do that well.
Environment variables are cached in rc, and this cache is never updated.

I think a good change would be that, by default,
rc performs `rfork(RFENVG);` at startup, then continues as it does now.
Then, there would be a flag that skips this rfork, and also disables caching
of environment variables.
