I'm all for fixing the problem in wpa_supplicant, and it should be
plenty clear that I believe that except for the little auth-while-auth
thing, the bug _is_ in wpa_supplicant.

However, it's not my decision. I'll fix the auth-while-auth eventually,
but I believe it is not really the problem in your case.
