    Yeah, that would work too in most cases - except if there's no VFS connection
    between tracer and tracee. (as it might be in the case of say chroot environments,

    I think it's better to have kernel solutions that dont modify the VFS beyond the session info. A task could thus generate a user-space event without
    having to negotiate with the tracer.
