statistics from some cpus don't fit 

Cpu statistics from time_in_state does not fit
in the data structures in ProcessState.java. The
time_in_state file eventually becomes larger than
the buffer of 256 bytes witch cause missing data
in the result or a NoMoreElementsException when
parsing the data.
The numger of cpu speeds can be larger than the
MAX_SPEEDS limit.

Solution
Make sure that the whole file gets read and increase
the MAX_SPEEDS that the system can handle.
