Is it worse than Javascript?

I do think a lot of production Python code implicitly depends on the GIL and would need rework for multicore. For example, code that expects "n += 1" to be atomic, because the CPython bytecode interpreter won't switch threads in the middle of it. -- http://mail.python.org/mailman/listinfo/python-list
