Using PythonKit in multi-threaded app crashes app

For several reasons it is required to call the python functions from parallel threads, currently PythonKit library is being used for that. While one python module is running and if I try to execute the other module from other thread than it is giving EXC_BAD_ACCESS error. this error from internal code of PythonKit.

Please guide me if I am missing something.
