Do you have to monkey-patch at run-time? It might be better to simply patch your Python installation once, and then have the change deployed globally. Given that it was applied to 3.2, I doubt it's going to break much, so you can probably afford to just edit the file and have done with it. Alternatively, you may be able to put your own forking.py earlier in PYTHONPATH, and thus shadow the stdlib module. That might require you to shadow all of multiprocessing, though.

Monkey patch an entire file in a python package
This question is about python 2.7 on Windows 7 I am trying to use multiprocessing with freeze. It appears there is some bug when using multiprocessing on freezed python code on windows platforms. There is this patch which made its way to python 3.2, and works in 2.7: http://bugs.python.org/file20603/issue10845_mitigation.diff I would like to monkey patch it. Problem is, this patch is for forking.py, used by multiprocessing.Pools Multiprocessing is using forking.py to launch processes. I would like to monkey patch this way : import multiprocessing import multiprocessing_fixed multiprocessing_fixed: import multiprocessing.forking as mpf def prepare(data): [include fixed code for this method] mpf.prepare = prepare_pyz It's not working because forking.py is launched like a python module. How to solve this problem ? Thanks -- https://mail.python.org/mailman/listinfo/python-list
