    CLONE_FILES is an argument to clone(), I'm using pthreads and I don't
    know if LinuxThreads implementation of pthreads gives me control of
    how clone is called. Anyway, if I understand what CLONE_FILES does,
    it should be given to clone, because threads do have to be able to share file
    descriptors, probably. But not the locks!
