All broadcasts inserted into the TransmitLimitedQueue's B-tree data structure are supposed to be unique. If a new broadcast is inserted which happens to collide with a broadcast that is already present in the tree, the new one replaces the old one. This is not supposed to happen. But if a software bug, a cosmic ray or an id-generator rollover results in a collision happening anyway, the replaced broadcast is silently discarded without Finish() being called. Consequently, the application may leak resources or otherwise misbehave while it waits forever for a callback that is never invoked. Call Finished() on broadcasts that have been replaced by a newly- inserted broadcast to mitigate the negative consequences of breaking the interface contract.
