Public bug reported:
On Ubuntu 18.04 (and ,
Running 'pip install simplejson' or 'pip install PyOpenSSL' twice
crashes on exit because their shared libraries are overwritten while in use.
To reproduce:
$ sudo apt install python-pip
$ pip install simplejson
$ pip install simplejson

Running (on some machines, at least) under gdb is illuminating:
$ sudo apt install python-dbg
$ gdb python
(gdb) set args -m pip install simplejson
(gdb) run
Starting program: /usr/bin/python -m pip install simplejson
[Thread debugging using libthread_db enabled]
