...Personally, I prefer code freeze policy. Moving tags on individual files make things messy, and global freeze gives everybody an opportunity to stop for a second, take a look at what we are going to release, and may be fix a bug or too...
I'm with Vadim - technically I like Berin's proposal with CVS tags a lot, but from the team's perspective it might be better to actually freeze development for a while.
And if "code freeze" = "frantically test everything before release", all the better.
