hobbitclient on solaris: using iostat for cpu stat

[Gianluca Rossi <grossi (at) acantho.net>]

Hi Henrik,
I have seen that hobbit clients collects cpu stats via vmstat, now i 
think that the cpu information provided by "iostat -c" is more accurate, 
because it has the "%waiting for i/o" columns, wich is also in the linux 
version of vmstat.
do you think you can add this information?
