Hi Robie, The pid I posted didn't exist on the system anymore when you asked.
I took a "snapshot" of current pids, ran the scp from remote again, this time the pid in question was 31397, and that, too, appears to be transient. After ssh-agent died that pid didn't exist anymore. Any cunning plan on how to track this down?
