Yep, the more easier and straightforward the approach, the better: threads are always (programmers')-error-prone by nature. But my question would be: does it REALLY need to be simultaneously: the CPU/OS only has more overhead doing this in parallel with processess. Measuring sequential processing and then trying to optimize (e.g. for user response or whatever) would be my prefered way to go. Less=More. regards, Marco -- http://mail.python.org/mailman/listinfo/python-list
