I can reproduce the problem under Windows 7. Thank you for your example and
description -- they were very helpful.
Detection that the original parent was PythonService.exe is necessary to avoid
undoing the paths set appropriately for running under a service. The current
code only detects the immediate parent.
Modifying get_preparation_data() in lib/multiprocessing/forking.py to perform
an additional test on the inherited values from the original parent's sys.argv
(available via the preparation_data key 'sys_argv') would resolve this:
if not d['sys_argv'][0].lower().endswith("pythonservice.exe"):
....
Potential complications to existing code appear very unlikely given its nature.
Patch forthcoming after running tests unless someone wants to beat me to it.
