PyEval_EvalFrame

[bretthall]

I see a C/python program that we're using spending a lot of time in
this function, far more than we think it should. What is it?

Thanks in advance! There seems to be nothing (but a bunch of stack
traces) when I google this.

PyEval_EvalFrame is the heart of the CPython interpreter: it's a very
large function that _implements_ the interpreter, marching through the
byte codes and executing them. You can't run Python code at all
without it.

Thanks in advance! There seems to be nothing (but a bunch of stack
traces) when I google this.

It's rarely called directly, but is called indirectly by everything
that runs Python code.
