[python-win32] wmi: processor class seems slow

[Alex Hall]

I do specify the field(s) I want, but this has not significant affect
on processor-related information access times. I will upload a zip
file of the entire thing, including dependencies, to my site soon and
will email the list with the above question (for reference) and a link
to the zip file. Thanks.
