Looks good, pushed, thanks.

We can improve the grep_logs function and instead of sleeping for 10
seconds before we call it, we could grep the logs in a loop ten times,
do 1s sleep at the end of the loop and exit with pass once the expected
logs are found and with a failure once we are out of iterations. That
should save ~20 seconds of the test runtime.
