- * OS X DTrace script to record the CPU time consumed by any python2.7 or SSH
- * process, and the exact read/write sizes to any AF_INET socket opened by an
- * SSH process.
- *
- * This introduces significant tracing overhead of between 5-10%, most likely
- * due to the SCHED events.
- *
- * Produces a CSV file containing columns:
- *      - wall_nsec: Nanoseconds wall time.
- *      - op: One of START, SCHED, EXIT, READ, WRITE 
- *      - nbytes: for READ/WRITE, size of AF_INET data read/written
- *      - cpu_nsec: for SCHED, nanoseconds spent scheduled.
- *      - pid: Process ID.
- *      - execname: argv[0]
- *
- * Operations:
- *      - START: thread relevant to the trace started up.
- *      - EXIT: thread relevant to the trace ended, cpu_nsec contains total
- *        time scheduled
- *      - SCHED: thread relevant to the trace was scheduled, cpu_nsec contains
- *        time spent before it went off-cpu again.
- *      - READ: SSH process performed a nbytes read from an AF_INET socket.
- *      - WRITE: SSH process performed a nbytes write to an AF_INET socket.
