I know that "proc" absent in OS X, but can you show an alternative? Examples: strings /proc/PID/environ -will show us variable environments of process. file /proc/PID/cwd -will show us working catalog of process. stat -c %z /proc/PID -will show us when the process is started. cat /proc/PID/status -will show us who is the owner of this process and more. Possibly in OS X too there is such place where it is possible to learn a lot of things about process?
