OK, this appears to be a serious regression that breaks virtualenv.
Steve Dower suggested a workaround on the tracker, but I don't think
that can be made to work in the case of virtualenv (for reasons not
worth explaining now, ask me if you want the details though).

Given where we are, what is the way forward here? I'm not entirely
sure what I should be saying to the user who reported the bug in
virtualenv. I think I'll recommend downgrading to 3.3.3 for now, but
it would be good to be able to give an idea of what the longer term
solution is likely to be.

Thanks
