This version is safer and a tad more flexible, just in case there is an 
exception (e.g. because of thread interruption):

def tail(file, interval=1)
   raise "Illegal interval #{interval}" if interval < 0

   File.open(file) do |io|
     loop do
       while ( line = io.gets )
         puts line
       end

       # uncomment next to watch what is happening
       # puts "-"
       sleep interval
     end
   end
end

Cheers
