I wouldn't mind having a little more breathing room. It's frustrating

nothing terrible will happen if their fixes get delayed to 3.9.

First, I want to say: I'm very happy with PEP 558's changes to
f_locals. It solves the weird threading bugs, and exposes the
fundamental operations you need for debugging in a simple and clean

You don't necessarily need rpath actually. The Linux loader has a
