This fixes the `ssh` proxy process not being notified when the proxy process dies. Turns out that the server would have stdout/stderr/stdin connected to the grand-parent ssh process connected to it and as long as the server kept running (even once it was daemonized into the background) the grand-parent ssh process wouldn't exit. That in turn meant that the Zed client wasn't notified when the proxy process died. Release Notes: - N/A --------- Co-authored-by: Bennet <bennet@zed.dev>
