/*
 * minfbypid.d - minor faults by PID.
 *               Written using DTrace (Solaris 10 3/05)
 *
 * This program prints a report of minor faults by PID. Minor faults are
 * an indiction of memory consumption. This script could be used to help
 * determine which process was consuming the most memory during the sample.
 *
 * $Id: minfbypid.d 3 2007-08-01 10:50:08Z brendan $
 *
 * USAGE:	minfbypid.d		# hit Ctrl-C to end sample
 *
 * FIELDS:
 *		PID		process ID
 *		CMD		process name
 *		MINFAULTS	number of minor faults
 *
 * This is based on a script from DExplorer.
