    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

"""I suspect that there is a race condition in datetime module.

When I ran the following code in a multi-threading application:

    datetime.datetime.strptime('20120509100335', "%Y%m%d%H%M%S")

I've noticed the following error in the log.
