    ExternalData: Improve robustness on Windows to copy a data object to a file · d3498603
    Brad King authored
    When an external data object was recently created on disk, perhaps
    fetched by the current process or another process, it may be
    inaccessible on Windows for a short time.  Tell our `file(COPY_FILE)`
    call to retry a few times to copy the object to the final file path.
    
    Hopefully this will resolve our long-standing spurious failures of the
    `Module.ExternalData` test on Windows.
