Summary: reload(os) fails for os.environ

Initial Comment:


I used function KERNEL32::SetEnvironmentVariableA 
via Dynawrap.dll from
http://cwashington.netreach.net/main_site/
downloads/default.asp?topic=a-m
to add an new entry.

Then I tested the result with a scripting host 
component and the new entry was shown. But not working 
was this:

reload(os)
os.environ
