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?
