Summary: Make os.environ.copy() return a copy
Initial Comment:
As reported by Jeff Epler in python-list:
"""
Under Python2.1 and earlier (back to 1.5.2):
>>> import os
>>> os.environ.copy()['COPY_HUH'] = "not really"
>>> print os.environ['COPY_HUH']
not really
Under even 2.3a0 (CVS):
>>> import os
>>> os.environ.copy()['COPY_HUH'] = "not really"
>>> os.system("echo $COPY_HUH")
not really
0
"""
This patch fixes this behavior, by returning a real
dictionary from the copy() operation.
