The next might be "__getattribute__ mechanism has surprising behaviour in common use-case" (which itself would imply having a use case where any of this mattered). This one might actually result in some productive discussion regarding a fix.
Your second reply is basically a doc bug, one of "__getattribute__ optimization is not specified in the language reference" or "__getattribute__ optimization causes non-comformance with the language specification", either way, you would get the attention of the few people who can actually help you, rather than attention from the many more who can't
As it is, the title at least primes the reader to think you are asking for what you go on to describe.
