Martin said it but nevertheless it might not be true. We observed similar very bad behaviour -- in a Web application server. Apparently, the standard behaviour is far from optimal when the system contains a large number of objects and occationally, large numbers of objects are created in a short time. We have seen such behaviour during parsing of larger XML documents, for example (in our Web application). Dieter -- http://mail.python.org/mailman/listinfo/python-list
