[Python-Dev] What's the story on Py_FrozenMain?

[Eric Snow]

While looking at something unrelated, I happened to peek at
Python/frozenmain.c and found Py_FrozenMain().  I kind of get the idea
of it, but am curious what motivated the addition and who might be
using it.  The function is not documented and doesn't have much
explanation.  I'm guessing that not many are familiar with it (e.g.
http://bugs.python.org/issue15893).

FWIW the function was added quite a while ago (and hasn't been touched
a whole lot since):
