Ok problem solved. For every class that the autoloading system is not able to found, the symfony sfAutoload::autoloadAgain() method flushes the autoload cache and recreates it by parsing the project directory structure (in debug mode only) before trying to look for the class again. This allows developpers to create new classes in a project without having to clear the cache. But it takes time and the bug was that the reloading occurred for every class that were not found. Most of the time, it's not a problem, because a class not found is a fatal error. But Doctrine tries to load some classes with different naming patterns, and if a pattern does not work, it tries another one. So, a class not found is not a fatal error.
So, I fixed the autoloadAgain() behavior in symfony (http://trac.symfony-project.com/changeset/8702) and Doctrine now tries to load the most sensible class first (http://trac.phpdoctrine.org/changeset/4316).
