The test suite runs quite a few child processes. The way coverage is collected, any code that is run in these child processes does not count towards coverage in the report that is ultimately generated.

This makes some covered code appear uncovered. This makes the coverage reporting performed by CI less useful since reports of uncovered code must be manually investigated to determine if they are really uncovered or if they are covered in a child process.
