      3  * minfbypid.d - minor faults by PID.
      4  *               Written using DTrace (Solaris 10 3/05)
      5  *
      6  * This program prints a report of minor faults by PID. Minor faults are
      7  * an indiction of memory consumption. This script could be used to help
      8  * determine which process was consuming the most memory during the sample.
