> Connection::isWorkAvailable accesses its FlowFileQueue without proper
> locking, resulting in unsynchronized access to the queue and a race
> condition. I was lucky enough to get a segfault when comparing the penalty
> expiration of a flow file from the top of the queue that has already been
> destructed and its memory released back to the OS.
