And with Christmas coming up, it makes things even worse. There are a few days before Phase III starts to have some progress on them. But if they don’t make it, then we’ll have to release without them.

The balance between the severity and how many people are (potentially) impacted by it. Then you should keep in mind that we have a 6-month release cycle. So any bugs that aren’t fixed now will hopefully be fixed by then.
I think you're doing an awesome job and I don't disagree with anything 
you've written.. curiosity killed the cat though..

I'm curious about why... release early, release often? stakeholder 
pressure or just trying to maintain a predictable release schedule

If it wasn't affecting anyone - there wouldn't be a bug report. I won't 
speculate how many people that is though or the severity.. (Once again 
it's not a critique or disagreeing. ALL software has bugs.. just 
I'd love to see a policy added to the Release page about who and what 
constitutes a release blocker. (Something so bad that schedules be 
damned that it needs to be fixed) At this point there's a 3.4 Release 
branch being worked on and trunk is open for destruction... now() vs 
January() who loses?
