Just thinking out loud as I haven't had time to read this patch
carefully, but I wonder if there's a potential performance problem
with ref_is_denied_case_clone(). What if the receiver repo has 60k
refs? Should we use name-hash (or a variant of it)? What if the sender
pushes 60k refs in one go, will ref_is_denied_case_clone check against
existing refs only, or it will cover more and more refs from the 60k
input?
