It actually finally completed. Doing it again with the proper PID as suggested provides the following:

    I think you've grabbed the "sudo" process, rather than the child
    "diskinfo" process.  If you use "ptree" on the pid first, you'll be
    able to see the full tree of processes.
    
    
    Cheers.
