Those are still heavyweight threads requiring context switches to switch from one to another. If you look at the multi-threading benchmarks in the Alioth shootout, languages with lightweight threads (such as Erlang or GHC) can switch orders of magnitude faster than those that use kernel threads. -- http://mail.python.org/mailman/listinfo/python-list
