ipython 下的 Python 2.7 中的 KeyboardInterrupt 不可预测，如何使其*始终*中止当前评估？
我正在编写 python 代码来进行数值分析，并且我一直使用 ipython 或 ipython -pylab 作为我的命令行界面。我经常遇到某些代码运行异常缓慢的情况，我需要停止它。然而，Ctrl-C 是有问题的；有时它有效，有时它什么也不做，有时它会退出整个过程（非常烦人。）我怎样才能做到让按Ctrl-C总是总是 有效吗？似乎它不起作用的时候是在其他模块中执行代码的时候。
非常感谢。
I'm writing python code to do numerical analysis, and I've been using ipython or ipython -pylab as my command line interface. I often run into situations where some code is taking for-freaking-ever to run, and I need to stop it. However, Ctrl-C is problematic; sometimes it works, sometimes it doesn't do anything, and sometimes it quits the whole process (very annoying.) How can I make it so that hitting Ctrl-C always always works? It seems as if the times that it doesn't work are those where it is executing code in some other module.
Thanks much.

您可能正在运行一个正在吞噬信号的后台线程，没有真正的方法可以禁止这种情况，请比较 http://www.dabeaz.com/python/GIL.pdf
You are probably running a background thread that is swallowing the signal, there is no real way of prohibiting that, compare http://www.dabeaz.com/python/GIL.pdf
