It may be a bug, and it may be worth fixing. I suspect the above
involves multiple allocations rounded up to the next highest power of
two (512MB) by the C library.

But it's actually better that people run into the memory limitations
on their initial commit of the file than on the second. They're also
not going to be able to check that file out on a machine with 512MB of
RAM, which may also be an unpleasant surprise.
