This PR is not the cause of the build failure. I was going to merge, but reckon that y'all might want to take a look at what's going on with lint.

I'll try to fix the broken coverage in pyramid.compat.

[stevepiercy]

Actually I won't make an attempt to fix compat. When I ran coverage with xml -i, there were too many missed statements, and I should talk with someone before I fix something that ain't broke.

[stevepiercy]

Lint is now passing. However the coverage report now shows two lines as misses.

try:
    import configparser
except ImportError:
    import ConfigParser as configparser

I checked both src/pyramid/compat.py and tests/test_compat.py, but I have no idea what is the proper way to get the missed statements have coverage.

Slap a # pragma: no cover on the except?

Perhaps a new test in tests/test_config/__init__.py for configparser?

[digitalresistor]

The issue is that virtualenv has pulled in configparser from PyPI, which back ports the new configparser from Python 3.x to Python 2.7.

We need to slap a pragma: no cover on that. Previously on Python 2.7 configparser would fail to import, and we would fall back to importing ConfigParser.
