Benedict Elliott Smith commented on CASSANDRA-15358:
----------------------------------------------------
I'm afraid I don't know the answer to either question. I'm waiting for a
review for the fix to be merged into trunk, and maybe I can try to accelerate
that by poking some colleagues. However a stable release of 4.0 is probably
months away, given current community resources and where they are focused.
