Brandon Williams commented on CASSANDRA-16689:
----------------------------------------------
bq. so it doesn't seem a problem of interaction between tests.
On the surface it doesn't but in that case it was actually previous runs of the
same test interfering, which is the entire cause of the failures in all these
tests, since the bootstrapping (gossip-only) clients are sometimes being
expired due to the modified (1s) ring delay at just the right time to break
things.
With the ring delay changes removed these pass the 10k test:

but obviously doing that is too broad for all the tests. I will work on
another solution.
