So I wrote a little script (or a template for scripts) that runs the sudo job in the background (but preserves stdout/stderr) and relies on bash to clean up the job when you ^C the script. Only gotcha with this is that you may have to retype your sudo password when you ^C if your authentication has timed out by the time you get around to killing it.

#!/bin/bash

function cleanup()
{
    sudo kill $job_pid
    wait $job_pid
    exit 0
}

trap cleanup SIGTERM
trap cleanup SIGINT

sudo long_running_foreground_process &
job_pid=$!
wait
