> If the JVM runs out of file descriptors we can get into an unreliable state (similar
to CASSANDRA-7507 on OOM) where we cannot trust our shutdown hook to run successfully to completion.
 We need to check IOExceptions and appropriate Throwable to see if we have a FileNotFoundException
w/message "Too many files open" and forcefully shutdown the Daemon in these cases.
