    dma: prevent races from sharing fd between children
    
    On fork, fds are shared between children.  If two processes work on
    different recipients, but on the same queue file, they might get
    confused when the fd (and thus the offset) is shared.  Prevent this by
    re-opening the queue file after fork.
