Restarting the pip install of iPython eventually worked.

Pip didn't try to redownload either of the packages it previous hung on, so I guess the download was successful.
I don't know whether pip is running anything via a subprocess.

However, once I fire up the newly installed 3.12 iPython, it comes up, but hangs the same way if I just hit enter at the prompt.

--- Process 31388 (pid: 4569), exception c0000005 at 0000000000000000
