What does this PR do?
This PR fixes a flaky spec introduced by #3929: a spec to check that an error was raised in a background thread implicitly depended on a race (that the background thread ran before the rspec thread did) and thus started failing when the race was lost.
By actually synchronizing with the background thread using the
on_failure_proc
, we now guarantee that the background thread has the chance to run as expected.Motivation:
Our goal is to always have zero flaky specs in the profiler!
