Since open and read procfs task stat often cause performance
degradation in the case that many process drivers are frequentyl
set control. To reduce this overhead, now initial stats are retrieved
by taskstats and 'pgid' which cannot be retrieved by taskstats is
get lazily once at the first reading.
