    Refactor and fix dummy process fixture

    Extracting the test fixture that creates a new process and leaves it
    running for a given amount of time into helpers where other fixtures for
    functional tests live. This both keeps the fixtures at one place and
    increases visibility of the fixture so that it can be reused in other
    tests. At the same time, the fixture is fixed as the original code
    omitted starting the process.
