Thanks, this looks like the right thing to do.

You had mentioned earlier in the thread the possibility of just dropping
the close() in git_transport_push. I agree that it is not worth going
that route, as it serves as a safety check to avoid leaking in early
returns (and indeed, in both the fetch and push cases, we can return
early without spawning a subprocess when the receiver already has all of
the necessary objects).
