How do you use multiprocessing with this?

OS: Windows 10 64 bit. Python 3.6.6 v3.6.6:4cf1f54eb7 64 bit Nuitka: First tried stable then tried the development Nuitka 0.5.33rc5 Python3.6 64 bit MSI I installed it with that. Short example:

import multiprocessing
import time

class Test(object):

    def __init__(self):
        self.process = multiprocessing.Process(target=self.run, args=())
        self.process.daemon = True

    def start(self):
        self.process.start()

    def stop(self):
        self.process.terminate()

    def run(self):
        while True:
            print('Never happening')
            time.sleep(1.5)

Test().start()

The error changes based on what the process is doing. Example:

Traceback (most recent call last):
  File "test.py", line 28, in <module __parents_main__>
  File "test.py", line 15, in start
  File "multiprocessing\process.py", line 105, in start
  File "multiprocessing\context.py", line 223, in _Popen
  File "multiprocessing\context.py", line 322, in _Popen
  File "multiprocessing\popen_spawn_win32.py", line 65, in __init__
  File "multiprocessing\reduction.py", line 60, in dump
TypeError: Can't pickle instancemethod objects

My program (closed source):

Traceback (most recent call last):
  File "app.py", line 233, in <module __parents_main__>
  File "multiprocessing\spawn.py", line 74, in freeze_support
  File "multiprocessing\spawn.py", line 99, in spawn_main
  File "multiprocessing\reduction.py", line 82, in steal_handle
OSError: [WinError 87] The parameter is incorrect

Whats the correct way to build a standalone with multiprocessing?

I used this (and many other combinations before that)

nuitka test.py --standalone --recurse-all --python-flag=no_site --plugin-enable=multiprocessing --recurse-plugin=multiprocessing --show-modules

Awesome work!
