\cprotect\note{

   Another very useful utility is \textbf{iotop}, which must
   be run as root. It displays a table of current I/O usage
   and updates periodically.

   Please note that the \textbf{be} and \textbf{rt} entries in
   the \textbf{PRIO} are explained in the \textbf{ionice}
   section, and stand for \textbf{best effort} and
   \textbf{real time}.
