The random number generator is initialized once, when the module is first imported. Forking simply duplicates the process in its current state, so no reinitilization occurs, both (or all) processes' generators are in the same state, and therefore generate the same sequence. -- Alain. -- http://mail.python.org/mailman/listinfo/python-list
