In this post I'll explain how to expand on David Beazley's cobroadcast pattern by adding a join capability that can bring multiple forked coroutine paths back together. I'll apply this technique to create a modular Python script that uses gcov, readelf, and other common unix command line utilities to gather code coverage information for an application that is being tested. Along the way I'll use ImageMagick under Ubuntu 12.04 as a running example.
