Currently, remote-curl acts as a proxy and blindly forwards packets between an HTTP server and fetch-pack. In the case of a stateless RPC connection where the connection is terminated with a partially written packet, remote-curl will blindly send the partially written packet before waiting on more input from fetch-pack. Meanwhile, fetch-pack will read the partial packet and continue reading, expecting more input. This results in a deadlock between the two processes. For a stateless connection, inspect packets before sending them and error out if a packet line packet is incomplete.
