Thanks to a PR from Ammar Askar we now run Python under lcov as part of the code coverage build. And thanks to codecov.io automatically merging code coverage reports we get a complete report of our coverage (the first results of which can now be seen at https://codecov.io/gh/python/cpython).

And funny enough the coverage average changed less than 1%. :) Nice! One thing I noticed, code that's Windows-specific isn't covered. I assume that's because the coverage reports are based on runs of the test suite on Linux. Is it possible to merge in data from the Windows test runs? If not, what's the best way to address this? Should we be mocking things to attempt to test Windows-specific code even on Linux, or should we simply accept that we're not going to achieve 100% coverage and not worry about it?

AFAICS lcov is based on gcov which is GCC-specific.
