### Ztunnel Shutdown Implementation

The key to this "handoff" between Ztunnels is `SO_REUSEPORT`, which Ztunnel by default sets on all of its listeners.
This enables multiple processes with the same effective UID to bind to the same port (see `man 7 socket` for details).
Linux will then send new connections to one of the processes (first to accept wins, so effectively random).

   * <p>This method does not alter the state of this {@code CacheBuilder} instance, so it can be
   * invoked again to create multiple independent caches.
