Someone forgot to add threading.py module in
libpython3.4-mininal_3.4.0-2ubuntu1.1 package. I fail when trying to
work with python3.4 in trusty-security environment.

How to reproduce:
1. Install new Ubuntu Trusty WITHOUT online updates or downgrade all packages to trusty-security.
2. Disable *-updates repositories, update apt cache:
# sed -i -e'/-updates/s/^/# /' /etc/apt/sources.list && apt-get update
3. Upgrade python3 packages:
# apt-get install python3 python3-minimal python3.4 python3.4-minimal libpython3.4-minimal libpython3.4-stdlib
4. Try to import threading module (will fail):
# python3 -c 'import threading'
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named 'threading'

Without threading.py `pip3 install` and `add-apt-repository` will fail.
Extended terminal output (including apt-cache policy) is in
python3.4_trusty_bug_terminal_output.txt . This problem has occured in
https://bugs.launchpad.net/ubuntu/+source/python3.4/+bug/1503382/comments/4
, but hasn't been articulated or resolved.

I compared packages in security and updates and found significant differencies:
1. [debian/pymindeps.py] subprocess key in excluded_imports is threading in security and dummy_threading in updates.
2. [debian/PVER-minimal.README.Debian.in] Information about threading module differs.

I make patch libpython3.4-minimal_3.4.0-2ubuntu1.1custompatch1.patch and
applied to python3.4_3.4.0-2ubuntu1.1 . The result is available in
https://launchpad.net/~bugchecker/+archive/ubuntu/python3-threading-
trusty-sec . This patch may be incorrect but it works for me.

Also I attached docker context for any experiments.
