I sent this out as a Google Doc a while back, but I just did a proof-reading, converted it, and pushed it live to the python.org: http://www.python.org/dev/workflow/ . So now people who ever triage issues have a guide to follow if they are not sure how to set things.
P.S.: Doing this doc has made me realize that our issue workflow still feels off and SF-influenced. If people want to talk at PyCon about it just let me know. I might try to get a discussion going during the language summit or at the sprints as I have some ideas on how to simplify thing but make it usable for more people (preview: I like how http://code.djangoproject.com/querydoes their tickets).
