You should be aware that using relative imports (or absolute imports) in the
standard library may cause custom __import__'s that don't take the optional
fifth argument to break, whereas using 'old-style' imports does not. I don't
know how common custom __import__ hooks are, and adding the optional fifth
argument is backwardly compatible, but I would personally not add absolute
or relative imports to the oft-used parts of the stdlib until after 2.5.

On the other hand, code using sys.path_hooks (like zipimport) don't need any
tweaking, as the absolute/relative choice is made before they are queried,
so I don't know howmuch impact this has, all in all.
