Two optimizations are possible:

• is_absolute() can pass theunnormalized path toos.path.isabs()
• absolute() on an empty path (orPath.cwd()) can avoid joining an empty string onto the working directory (thus avoiding a call toos.path.join()), and short-circuit the string normalization (as the result ofgetcwd() is fully normalized)
