> For example, when starting a newly installed Cassandra node for the first time, if the
seed is down (and the current node is not a seed) a RuntimeException gets thrown by the Gossiper
with "Unable to gossip with any seeds", and Cassandra subsequently shuts down.
> The issue is with the StorageServiceShutdownHook thread which, if any exception is thrown
as it's executing, will miss the remaining steps in the shutdown process.
> Here's a log fragment.
