What release tasks do you think there are that are not directly
proportinal in effort to the length of the release cycle? I don't see
how the release critical bug criteria question is relevant here: with
3-month cycles, the amount of blocker bugs per release should be half of
the amount of blocker bugs per release with 6-month cycles,
independently of what the criteria are for blocker bugs.

Getting changes faster to the general public will of course make the
bugs in those changes to become visible faster. As for diminished amount
of release candidate testing with more frequent releases: at least I
don't do any extra testing during release preparations, so more frequent
releases wouldn't impact my contribution to the testing. (To be clear, I
don't consider my contribution to testing to be zero: I always run a
development version of Pulesaudio on my computer, so the features that I
need in my limited personal use cases are continuously getting tested.)
Are there any people ("testers") who regularly run some test set on
release candidates? If there are such people, for them more frequent
releases would increase the workload, which might lead them to stop
doing what they are now doing. I'm not aware of any such people, but
maybe they just don't keep much noise about themselves.
Then there are distributions that might push the release candidates to
their users. I think these are the most valuable release candidate
testers. For the distribution maintainers, increasing the release
frequency would again increase the workload, possibly leading to them to
stop caring about the release candidates. I don't have any idea how
likely that scenario is. Your experience would be one data point: let's
say that the release cycle was 3 months, and PA 4.0 would be released
soon after Ubuntu 12.10, would you bother pushing the release candidates
for 4.0 to Ubuntu, knowing that 13.04 would probably end up using PA

I don't myself see the point of explicitly aligning to Gnome or KDE or
anything else if they don't ask for it themselves. As long as you, as an
Ubuntu representative, remain the only person who has opinions about
PulseAudio release dates based on hard facts, I don't mind aligning to
Ubuntu at all. If other distributions start giving similar input, we can
then do a compromise between them and Ubuntu, until there are so many
conflicting wishes that a compromise becomes impossible and we can start

No, I haven't seen any bad attitude from you :)

If you really think that hard release dates are useful, we can increase
the freeze length until we start reliably hitting the release dates. The
alternative is that you ignore our stated release date plan and make
your own guess about how long the process will take after the freeze
date. I'm not sure if there's a big difference, and either one is fine
The third alternative is that everybody promises to work harder to make
the freezes nice and short, and then meet those promises. But at least I
won't make any such promises.
