Actually, any kind of container object would do: you could pass a list, 
dictionary, or class to the thread, and the thread could store its results 
in it.

A hackish method would be to pass the dictionary returned by locals() in 
module1 to the thread. This way the thread could set a value in module1 
directly.

Just don't forget to .join() on the thread in module1 before accessing the 
container object! (Assuming you're using threading) I just wish Python's 
.join() could return values, like pthread_join can.
