No I didn't. :) Okay so it only uses 4.6MB of memory and it runs at the same speed: there's no problem with chaining tee objects as long as you discard them. If you don't discard them then a script like the one I wrote would quickly blow all the system memory. Oscar -- https://mail.python.org/mailman/listinfo/python-list
