My initial reaction was that "come on, we already agreed to use 4
months", but then I remember that the "agreement" was done in a private
discussion. So, reopening the cycle length discussion is OK. My opinion
is that the shorter, the better (to a limit, of course, but e.g. 2
months would be fine to me). But more important than the cycle length is
that we have time-based instead of feature-based release model, so I had
no trouble of settling with 4 months in the previous discussion. I could
easily live with 6 months too.

That's what happened with Nokia's Maemo 6, which was rebranded as Meego
1.2 Harmattan (the "real" Meego used a sligthly newer version), but I'd
hope that it's not that bad everywhere... I think Maemo 5 had pretty
fresh PulseAudio at the time of release.

Speaking for myself, I don't think I have the required discipline. I'm
good at making plans about how to spend my free time, but I'm pretty bad
at following those plans.
If we had 3-month cycles, the amount of work needed to polish a release
should be smaller, so the delays should be shorter too, and even in case
of a badly delayed release, you'd get newer PulseAudio version in Ubuntu
than with a badly delayed 6-month cycle.

So far there hasn't been any formal criteria for blocker bugs.

If a policy causes unreasonable delays, it's a bad policy. But as I
said, we haven't had any policy so far.

I don't really see how the mission could affect the release schedule,
unless the mission is something like "contribute to distibution X's
success by fulfilling all of its sound server needs". If the mission is
to cater to some specific distribution, then it of course makes sense to
align as well as possible to that distribution's schedule, but I don't
think anyone is suggesting such mission.
I don't mind discussing the mission and vision, it might very well be
beneficial, but maybe it should have its own thread?
