Actually, Nicolas put quite a bit of work into multi-threading the
repack process; the results have been in master for some time, and will
be in the soon-to-be-released v1.5.4.
The downside is that the threading partitions the object space, so the
resulting size is not necessarily as small (but I don't know that
anybody has done testing on large repos to find out how large the
difference is).
