[Python-Dev] Python 2.3 release schedule

It's unclear there whether you intend that a warning in 2.3 be coupled with
(a) delivering the 2.2 result, or (b) delivering the new (auto-overflow)
result.  If a _future statement is introduced for this (incompatible changes
are what __future__ is there for -- alas), #a is the obvious answer.

Nuking SET_LINENO remains the conceptually clearest way to get a >5% boost
in pystone.  As other high-frequency paths in the interpreter have gotten
leaner, the speed benefit of -O has gotten larger.
