As described in Issue9517, many test modules do not make use of the helpers in script_helpers.py to invoke the python interpreter in a subprocess. Issue9517 will be broken down into several smaller issues so we can address smaller change sets.

This issue is to update _test_multiprocessing.py to use script_helpers.py.

I am working on this!

Updated both tests in _test_mulitprocessing.py which were using sys.exectuable and Popen to use script_helpers instead, refactored script_helpers a bit to make this work.

run_python and spawn_python are basically the same, I need to reconcile those.

Now using existing function spawn_python instead of creating a new function.

If #18576 gets merged before this does, I have some updated docs for the new helper functions.

Thanks for the patch.  I left a review on Rietveld.

Sorry but these patches have been lost in the huge database of open bugs and we forgot it. They have been written 3 years ago. Since that, Python moved to GitHub. If you are still interested to convert tests to script_helper, please open GitHub pull requests. I would suggest to start with a small one, and then see if other tests should be converted. I close the issue. Reopen it if you want to work again on it.
