I've identified that doing module imports the first time in a newly spawned interpreter takes a long time, and hence I'm trying to save the state of a PythonInterpreter in an in-memory cache. I wasn't sure if reusing the same PySystemState would be thread safe, so I wanted to create a deep copy of it. Then, I would instantiate a new PythonInterpreter with a copy of cached local variables in the namespace (retrieved using getLocals()) and copy of cached PySystemState. Since PySystemState has many properties, I thought it would be safer to use serialization to get a deep copy.
