Hi [~elek]
{quote}Independent from the flakiness I think a test where the timeout is 8
minutes and starts 1000 threads to insert 500 buckets (500_000 buckets all
together) it's more like an integration test and would be better to move the
slowest part to the integration-test project.

I think now it should run quickly with the fix, and also I think it will not
take that much of time. On my local laptop, I see, it is always completed in
30sec.
And on github run I see it is completed in 53 seconds. I just want to keep this
test in UT, as this will detect any failure in the DoubleBuffer issue which is
a critical component in OM. (Why I want in UT, because we are going to force
sooner, UT should be always green)
