If we do this we need to make sure it will also work for the preferred default connection class - urllib3 in a consistent way. Once we figure that out this can be merged.

This is too specific a change. If you need something like this I'd suggest you subclass the connection class and override the __init__ method to call the super and then set up anything you might want.

Also consider using the urllib3 connection class, we have had much better results with it.

Thanks!
