Karl Vogel has an interesting discussion relevant to the bugzilla growth
and management issues from the 'abrt' debate. The blog is titled "Bug
Growth is Proportional to User Growth, and Bugs are not Technical Debt":
http://www.rants.org/2010/01/10/bugs-users-and-tech-debt/
He makes a point that for a growing project it doesn't even make sense
to expect zero or constant bugs---instead, the challenge is how to
manage the infinite growth.
