[Python] Avoid PicklingError using multiprocessing in Python 3.8 libreoffice macro

I'm trying to use multiprocessing in a LibreOffice Macro in Python 3.8. When I create a Macro it is part of the 'ooo_script_framework' module. So, when the process is pickled it is in fact part of an object which is not pickelable.

"Can't pickle \<function task at 0x0000017B53415AF0\>: import of module 'ooo_script_framework' failed"


I'd like to be able to make the function declared in the main process instead without any link to the module.

MyMacro.py :

import multiprocessing as mp
import time

def tack():
with open("./test.txt", "w") as f:
f.write("toto")

def MyMacro():
p = mp.Process(task)
p.start()
time.sleep(1)
p.stop()


It seems that MyMacro.py is somehow copied into something like ooo_script_framework.py.

ooo_script_framework.py :

insert MyMacro.py


How to make the interpreter not able to see ooo_script_framework.task(), but just tack()?
