Interesting point... One of the main reasons that I wanted this was that some programs rely on it NOT being there. Like "killall", etc...

+1 on providing a sys module interface for this so that programs can choose the name on their own.

Yeah, I was thinking about that one. It's kind of complicated, unfortunately. To do it right, you need to muck around with the original argv and envp arguments. So, it will cause side-effects to any code calling the main Python entry point if we do it in there... Besides, we really end the envp anyway (which Py_Main doesn't take).

So, I'm thinking there would need to be a new entry point like "Py_ArgsSetup(int argc, char ***argv, char ***envp)", which would need to be called to set this up. You'd call "Py_ArgsSetup(argc, &argv, &envp)", and it would re-allocate argv and envp, and use the original data space for storing the process string.

Thoughts?
