I guess this was on Windows 7, right?  I succeeded to do this on a
64-bit Windows 7 as well, and it took about 2 hours.  And now I
understand why git ran out of memory on Windows XP: the memory
footprint of git-pack-objects goes up to 3GB, whereas Windows XP has
only 3GB address space for all the applications.

So I guess we will need to repack the repository on savannah as a
prerequisite for switching, and then make sure it is repacked
regularly afterwards.  Otherwise, people with low memory and/or slow
CPUs will need many hours to do this on their local machines.
