[Import-SIG] Updated and deferred PEP 406 (ImportEngine)

[Nick Coghlan]

I just pushed a new version of PEP 406 (the ImportEngine PEP) to
python.org (http://www.python.org/dev/peps/pep-0406/).

Based on the previous round of discussion, I've abandoned the idea of
modifying the PEP 302 APIs and the PEP now suggests a decimal module
inspired mechanism for safely substituting elements of the global
import state.

However, I also declared that I won't be putting this forward for
serious consideration until 3.4 at the earliest. There's going to be
enough churn in the import system for 3.3 already without attempting
to add this on top.

Cheers,
Nick.
