Actually, I've been sleeping over this, and I think I'll go with the
environ shallow copy patch, because being extra paranoid it's safer to
not assume stuff like setenv() might not free the internally handled
environ array of pointers, if it detects it has changed. I'll also
use proper envsize instead of special casing the final NULL.
