Googling for Py_Finalize() suggests that the above may not be
advisable regardless of whether one uses Boost.Python or not.
That's fine, I can easily live with one global interpreter
whose state persists.

So what is the correct way to use Boost.Python in an embedded
setting? Is it safe to call Py_Initialize() once, then run scripts
using PyRun_SimpleFile(), and at the end just let exit() reclaim
the resources held by the Python interpreter?
