How to recover lost Python source code if it's still resident in-memory

I screwed up using git ("git checkout --" on the wrong file) and managed to delete the code I had just written... but it was still running in a process in a docker container. Here's how I got it back, using https://pypi.python.org/pypi/pyrasite/ and https://pypi.python.org/pypi/uncompyle6

Attach a shell to the docker container

Install GDB (needed by pyrasite)

apt-get update && apt-get install gdb

#!/bin/bash
line=$(tail -1 /var/log/myapp/myapp.uwsgi.log)
substr='uWSGI listen queue of socket'

if test "${line#*$substr}" != "$line"
then
	#We're using upstart, could be easily adapted to fx systemd
	# Adding a log statement to keep track of when this happens. Remember to create the monitor dir
	/sbin/initctl restart myapp > /var/log/myapp/monitor/uwsgi-monitor.log 2>&1
	echo "$(date) restarted myapp due to listen queue error" >> /var/log/myapp/monitor/uwsgi-monitor.log

# Here is an example of some syntax I'm proposing:
# See the github repo at https://github.com/mikeckennedy/python-switch

def test_switch():
    num = 7
    val = input("Enter a key. a, b, c or any other: ")

    with Switch(val) as s:
        s.case('a', process_a)
        s.case('b', process_b)
