Right. That won't work.

Multiple ModuleProvider is the right solution.

You can add a new runStaticConstructorsDestructors which takes a  
Module as argument and runs only the static initializers for the  
module. You can model it after the existing  
runStaticConstructorsDestructors. It should be pretty straight forward.
