1 Known issues/TODO (for steady-state)
3 - Does not work over a network connection
5 - Allow user to specify the frequency of measurements
7 - Better documentation for output
9 - Report read, write, trim IOPS/BW separately
11 - Semantics for the ring buffer ss->head are confusing. ss->head points
12 to the beginning of the buffer up through the point where the buffer
13 is filled for the first time. afterwards, when a new element is added,
14 ss->head is advanced to point to the second element in the buffer. if
15 steady state is attained upon adding a new element, ss->head is not
16 advanced so it actually does point to the head of the buffer.
