    Self-follow-up, hopefully useful.

    I truss the process running the POP tcpserver, then the process it
    forks when I connect to the POP port. I don't know if the ERR#9 is
    fatal, and unfortunately can't trace the next forked process 33323
    because the child crashes immediately after displaying the info.

    Does this help at all? Thanks.
