Ok after some testing, what the who -Hu is giving me is the idle time of
each running open shell. The first line always return a "?" as the IDLE
time.

ex:

NAME     LINE         TIME             IDLE          PID COMMENT
vg0619hl :0           2010-09-30 06:10   ?         13091
vg0619hl pts/1        2010-09-30 06:27 00:11       14084 (:0.0)
vg0619hl pts/2        2010-09-30 06:54   .         14084 (:0.0)
