Ok, after looking after the other changes I can state the following details:
* We had problems with PySystemState before, we use multiple and for 2.7.1 It worked best to use PySystemState from a ThreadLocal. So every thread with a script has his own state. 
The Python also uses a separated ClassLoader and Plugin Architecture, therefore we create multiple PySystemStates. 
* If I understand the comments correctly, multiple PySystemState is the wrong way. I can change and test if it works with just one.
* The import * is indeed for a bunch of static Utility-Methods that 
are provided by the Java class.
