The `__future__` we relied on is now, where the 3 specific things are
all included [since Python 3.0](https://docs.python.org/3/library/__future__.html):
* absolute_import
* print_function
* unicode_literals
* division
These import statements are no-ops and are no longer necessary.
On the bots, we have a timeout without output of 60 minutes for the entire test.
This should ensure that we are able to kill mis-behaving tests and give a good
error instead of just getting a jenkins timeout error.
For those confused, this is for the guard malloc/leaks test.

Replace the project global linting rule excludes (as defined in .pep8) with
fine-grained "# noqa" annotations.
By using noqa annotation the excludes are made on a per line basis instead of
globally.
These annotations are used where we make deliberate deviations from the standard
linting rules.
To lint the Python code in the project:
$ flake8
To install flake8:
$ pip install flake8
See https://flake8.readthedocs.org/en/latest/ for details.
To enable checking of the PEP-8 naming conventions, install the optional
extension pep8-naming:
$ pip install pep8-naming
To enable checking of blind "except:" statements, install the optional
extension flake8-blind-except:
$ pip install flake8-blind-except
To enable checking of import statement order, install the optional
extension flake8-import-order:
$ pip install flake8-import-order
Previously, we had some white listing lists for allocations that were assigned
into globals during a benchmarks running. Now we instead run two different
iterations with the second running an additional time. Then we subtract the
counts.
This enables me to get rid of the whitelist.
Make sure all Python code in the repo specifies which exceptions to
catch when using `except:`.
Regressions can be catched using `flake8-blind-except` going forward.
