When dealing with a packed\nrepository, it first asks individual objects (expecting they\nwould be found in $GIT_OBJECT_DIRECTORY/??/ directory), and when\nnot found it fetchs packs and looks inside. Recent commit\nwalker knows how to issue multiple requests while earlier\nrequest is still in transit, so you can expect some requests to\nindividual objects.
