Initialisation of domain specific settings happens too late.

The init code block is meant to be used to switch settings based on which domain is being accessed.

The primary use case I have for this is switching the theme , but the code is executed too late for the theme_default setting to be used.

The issue is however that the database isn't available at that point, so the data structure needs to be serialized and stored on the file system to be used.

I need to solve this before I can release a 1.0 release.
