Benjamin Lerer commented on CASSANDRA-17653:
--------------------------------------------
I had some look at the patch and considering that the issue might be a race
condition requesting the message and checking the value in 2 separate calls can
lead us to the wrong direction if the 2 calls return different results.
I also had a look at the code and it seems to me that there are at least 4
problems in {{ExpiringMemoizingSupplier}}.
