Nick Bailey commented on CASSANDRA-6920:
----------------------------------------
FWIW, I said "potential" fix because I didn't really know if there were
performance concerns adding that synchronized block on a method we call for
every read/write that comes in to the system.
Just wanted to mention that here in case there are concerns.
