My rule of thumb would be was a buffer generated "by" a file/action on
file in the project. The goal would be that if I open a project, do some
work and then call project-kill-buffers, and repeat this over 10, 100 or
however many (different) projects, that the list of live buffers doesn't
increase dramatically, or even proportionally to how many projects I
have used in general.
