23		* a total
24		* Takes several arguments :
25	<	* -d <number>  Takes the number of seconds to wait to get traffic sent since last call
26	<	*              Note, this is not disk traffic per second. Its the traffic since last
27	<	*              call. If you want it traffic per second averaged over time since last call

28		*              You need to divide against the time since last time this was called. The time
29		*              between 2 calls is stored in systime in the disk_stat_t structure.
