That part is actually somewhat new. We used to copy over all files we
downloaded, which I guess might trigger an update to access time or change
time (but not modification time). In WordPress 3.7, we now md5 files before
copying and only copy over files that were changed. End result is the same,
but it means faster updates, and more stability as there are less I/O

Pretty cool, I think.
