+     *       - Start IPC server (fork)
+     *       - Store IPC state (fork)

+     *         - Store IPC state
+     *     - Else Fallthrough
+     *   - Wait for a new IPC state for a maximum of 30 seconds, then throw
+     *   - Execute original request via IPC
+     *
+     * - If the session is locked
+     *   - In parallel (concurrent):
+     *     - The IPC server should be running, connect
+     *     - Try starting full session
+     *       - Fetch light state
+     *       - If don't need event handler
+     *         - Wait lock
+     *         - Unlock
+     *         - Fork
+     *         - Lock (fork)
+     *         - Deserialize full (fork)
+     *         - Start IPC server (fork)

+     *         - Wait lock
+     *         - Deserialize full
