Aleksey Yeschenko resolved CASSANDRA-5811.
------------------------------------------
Resolution: Cannot Reproduce
I believe that with the switch to git:cassandra-1.1 instead of 1.1.9 in the
dtests this is gone, or at least I can no longer reproduce it.
Feel free to reopen if this ever happens again.
