As a Windows user, I would like there to be one tz data file used by all 
Python versions on my machine, including ones included with other apps. 
I would like every installer, including for bug fix releases, to update 
it. This should be sufficient for 99% of Windows users. As Guido says 
above, the docs should tell the other 1% how to update it explicitly.
