Genode's general mechanism to destroy subsystems works as follows: When
the parent decides to destroy a subsystem, it closes all sessions that
were opened by the subsystem in reverse order. Naturally, those sessions
comprise, among others, all file-system sessions held by the subsystem.
>From the file system's point of view, this event looks like the client
issued a session-close request. The current approach would be to let the
file-system call sync each time when a file-system session is closed.
Currently, there is no separate mechanism in place to gracefully shut
