    [oiskuu]: I'm unfamiliar with android or SELinux. But I believe there is nothing of a kind. Unless you play with capabilities or build your own containers/ namespaces.
    [davido]: I am not finding closing STDIN to be an adequate means of making getlogin return undef.
    [Corion]: Maybe doing a double-fork (daemonizing) can make go that information away, but maybe not
    [Corion]: But I think my knowledge of unix/Linux datastructures is several decades out of date, so I don't really know what information it keeps on processes

    [tye]: I just daemonized and getlogin() still knew who I had been.
