What I'm planning to do is to make something that will rebuild and run
the tests on each of our commits, and compare results and time spent
with results from the previous commit. This should tell us for each test
failure (or increase in testing time), which commit introduced it.
Once we have those results, it should simplify the investigations, and
we can divide the task if needed.
