I also plan on adding a profiler_option file to let you sort by Hit, Time, 
or Avg. I'm working on a project at the University that would like to see 
that. Yes, it can be done by userspace too, but it is very simple to do in 
the kernel (just pick what to sort by since it already has the sorting 
algorithm). Userspace, can do it, but it is much more clumsy at it.
