This post was promised some time ago, about our paper published at the conference on Foundations of Software Engineering (2010), a top conference in software engineering. Instead of posting it here, however, Karthik (one of my student co-authors), posted a description of our FSE paper here: http://www.macesystems.org/2011/04/finding-latent-performance-bugs-in-systems-implementations-fse-2010/

The very short description: by building robust systems, we hide some of our correctness bugs, converting them into performance problems. Our paper is about using model checking concepts to discover such bugs with a minimum of developer effort. See the post and paper on the group website.
