It does not. The spawned processes use the command::

  python.exe -c 'from multiprocessing.forking import main; main()' --multiprocessing-fork [handle#]

And only after, the multiprocessing machinery overrides sys.argv with the same value as the initial process.
There is certainly some code in one of your modules that starts running the tests.
