Attempt to reduce flakiness of processes_lifecycle_test.rb

Hey @rosa 👋

This is an attempt to reduce the flakiness of processes_lifecycle_test.rb

Issue: #602

Well, that clearly didn't work lol

This is quite tricky! I ran it over 5k times locally, no flakiness.

I'm starting to think about alternative approaches, maybe we can use minitest-retry gem?

Sorry @p-schlickmann, I missed this one! Let's try a bit more to see if we can solve the ones pending, and then if not, we can try with minitest-retry. I'm worried that gem will, long-term, hide all the flaky tests and turn the whole test suite into something pretty slow 😅 (It has happened to me in the past).

Going to close this one, since this attempt didn't work. I'll keep working on this myself from time to time!
