What does this mean? That you can avoid pulling patches that cause
conflicts if they've already been applied? But that's not terribly
interesting in most logging or mass download applications.
While I quoted Hoare on the root of all evil elsewhere, and continue
to take that as my default position, these numbers are uncomfortable.
I don't care how cold the CPU cache is, I don't want an attempt to
access a non-existent local repo to take 10s. Nor should a
disk-to-disk copy of a 400MB directory tree take 23.5m. The partial
clone times are heartening, although it's hard to guess what they
mean in terms of throughput.
