They are flaky as they need to be updated every time the underlying implementation changes. By using 'grep --fixed-strings --file ' instead, we can check for the positive presence of lines we are sure should be happening, and ignore any additional things which may be happening around us (for example, additional child processes which are occurring unrelated to the code under test).
