futures 3.2.0

Backport of the concurrent.futures package from Python 3

This is a backport of the concurrent.futures standard library module to Python 2.

It should not be installed on Python 3, although there should be no harm in doing so, as the standard library takes precedence over third party libraries.

To conditionally require this library only on Python 2, you can do this in your setup.py:

setup(
    ...
    extras_require={
        ':python_version == "2.7"': ['futures']
    }
)

Or, using the newer syntax:

setup(
    ...
    install_requires={
        'futures; python_version == "2.7"'
    }
)

Warning

The ProcessPoolExecutor class has known (unfixable) problems on Python 2 and should not be relied on for mission critical work.
