However, if a new codec/whatever is quite buggy, it can generate an
avalanche of annoying bug reports until the next release.  If this
annoyance can be avoided by committing it a week or two later, then
nobody is harmed.

OK, I see that we need to set a few more dates on the way to 0.5.
Here is the timeline:

weekend 2009-02-07/08 freeze
weekend 2009-02-14/15 bug squashing
weekend 2009-02-21/22 release

So you still have about 10 days to go wild and have to hold your horses
after that.  Freeze means that you should be doubly careful and triply
confident about your changes.  Risky things will have to wait for two
weeks, that should not be a burden for anybody's patience.

If you do break the build or the regression tests or introduce bugs
during the freeze period, you risk being shamed in public, being passed
huge amounts of virtual Cola for immediate consumption and being made
the target of snide remarks on IRC and the mailing lists.  Clearly not
a situation you want to find yourself in, do your best to avoid it.

I kindly request skipping bikeshed discussions about procedural issues.
Let's get it done this way and analyze the results later.  If it ends in
catastrophe I'm prepared to accept the blame *afterwards*.

For now, let's try to see this as an experiment and focus on the
technical issues of getting the release out the door.
