[Python-3000] PEP: Eliminate __del__

["Martin v. Löwis"]

Socially, this is the point of the PEP process in the first place: the
PEP author is supposed to collect community feedback in the PEP, and
address it as necessary. People won't stop discussing if the PEP author
is away, but eventually, discussion will die off, and restart when a
new version of the PEP is published. Of course, at that time, people
will have their bias when the next version of the PEP comes, and you
can do nothing about that.

Procedurally, there is a problem that this still isn't an
officially-posted PEP, even though it's already several days
past the deadline. OTOH, it's listed in the PEP parade. Still,
I would like to see a posted PEP rather sooner than later.
Defending the deadline will be necessary in the future, and
that will become more difficult (on grounds of fairness) if
some PEPs get accepted that had their first appearance on
python.org/peps/ way after the deadline.

Martin
