The following are examples of running rb_stat.d on Ruby programs.
rb_stat.d shows you the number of events per second that have happened since
the last line output. The default interval is 1 second, but you can specify
other intervals as arguments to the script.
This shows the rb_stat.d script reflecting the Code/Ruby/func_slow.rb script.
# ./rb_stat.d
