The atexit docs (http://docs.python.org/library/atexit.html) are very confusing. In one place they say, "The order in which the functions are called is not defined". In another place, "all functions registered are called in last in, first out order". Which is correct?
Also, it's not clear how atexit handlers interact with threading. Do all handlers get called in the main thread? What if some other thread registers a handler? Does it get called in that thread? -- http://mail.python.org/mailman/listinfo/python-list
