With such finely intermingled thread activity, there might be a fair bit of spinlock spinning involved. Additionally, I suspect that the kernel does not track CPU time at microsecond precision and will tend to round the used times up. Obviously, this is not a reasonable way to use threads. The example is only effective at producing lots of overhead. _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
