An individual tag operation isn't expensive so much as is tagging *every single file* in the src/ hierarchy, essentially what we have to do at each major release. Adding "merge me" tags on a case by case basis would probably be a little different since you'd expect that to happen over a long period of time (the life of the branch you're merging into, basically) and to small collections of files in each instance. That'd make it much less of an impact on all those users out there who are cvsup'ing daily, and not quite what I was talking about below. I believe someone was asking why each SNAP couldn't be reproduced exactly by checking out a tree with the "snap tag", and to do that I'd essentially need to tag all the sources (and, if one wanted to be _really_ anal, the ports) once a day. That would be far too expensive and the lockdown time on the repository to create the tags would not be appreciated either.
