    initial v1  
    1 See how the test in test_storage that I mentioned doesn't store the entire large share -- just the part of the large share that would fall past the 2^32 cutoff.  Likewise, the test that I am proposing would upload just a few bytes at a large offset.  This wouldn't take hours to compute, but it would (momentarily) allocate more than 4 GiB of disk space, and if the OS doesn't support efficient sparse files then it would also fill in 4 GiB of disk space with zeroes.
