Yang Yang commented on CASSANDRA-3269:
--------------------------------------
bq. That could (should) not happen. The commit log is mono-threaded by mean of

this is no longer the case since it was changed (particularly getContext() ) in
https://issues.apache.org/jira/browse/CASSANDRA-3253 due to possibility of
deadlock
