[Python-Dev] Lib/http/client.py: could it return an OSError with the current response?

[Guido van Rossum]

If you can do it without breaking existing code that doesn't expect
the extra information, please go ahead! For things like this it is
typically best to go straight to the bug tracker (bugs.python.org)
rather than asking the list first -- if the issue turns out to be
controversial or mysterious it's always possible to go to the list
later at the advice of the person doing triage in the tracker.
