Why only two phases? I was thinking about the initialisation sequence a 
while ago and thought that a three or four phase sequence might be 
appropriate. What matters is that the state in between phases is well 
defined and simple to understand.

You might want to take a look at rubinius which implements most of its 
core components in Ruby, so needs a clearly defined startup sequence.

(Rubinius using 7 phases, but that would be overkill for CPython)

Cheers,
