Jacek Lewandowski commented on CASSANDRA-18710:
-----------------------------------------------
CASSANDRA-17071 relaxes some synchronization requirements for schema changes,
in particular some changes against one ks does not block some changes against
other ks. This might have changed some timings and made that race more
apparent. But adding those delays shows that the race is a problem on all
versions.
