bugid : 6207437
synopsis: iostat should display merged results.
path : /solarisws/usr/src/cmd/stat/iostat
According to 'man iostat'-->
" > The svc_t response time is not particularly significant when
> the I/0 (r/s+w/s) rates are under 0.5 per second. Harmless
> spikes are fairly normal in such cases.
"
i just added a merged response("header io") in the beggining.
each time the pgm adds r/s and w/s and print it as i/o.
