    include/tube: fix queue remove/add race · edb5af7f

    A receiver could get a spurious empty tube status, due to
    receive_tube() racing with send_tube(). See the added comments into
    the code for details about the resolution.
    At this chance, guard against load/store tearing on shared pointers.
    Pending issue: we still have a potential connectivity issue between
    the prep and finish ops when pushing to a tube.
