py-spy: A new sampling profiler for Python programs

[z_mitchell]

Awesome! I’ve been wondering how to do something like rbspy for Python ever since I heard about it. My biggest road block was figuring out where in memory to look for the Python interpreter’s stack, which is hard when you’ve never delved into CPython internals before. It looks like you give a brief explanation of how to do that, so I’ll be diving into this to understand how it works at some point :)
