At the following URL  
[http://groups.google.com/group/comp.lang.ruby/browse\_thread/thread/db](http://groups.google.com/group/comp.lang.ruby/browse_thread/thread/db)…

There is the following code

#!/usr/local/ruby-1.8.0/bin/ruby  
require ‘ftools’  
require ‘tempfile’

def compete who, f  
5.times do |i|  
f.flock File::LOCK\_EX  
f.puts format(“%s:%d @ %f\n”,who, i, Time.now.to\_f)  
f.flock File::LOCK\_UN  
end  
end

path = format( **FILE** + ‘.out’)  
fd = open(path, File::WRONLY | File::TRUNC | File::CREAT)

if fork  
compete ‘PARENT’, fd

Process.wait rescue nil  
open(path){|f| puts f.read}  
fd.close  
File.rm\_f path if File.exist? path

else  
compete ‘CHILD’, fd  
end

The code runs on my system. But, I don’t see any call to Tempfile.new.  
I’m assuming it’s implied? If it is being implied, where is it being  
implied at in the code?

tempfile isnt used as far as my knowledge goes…to test my theory?  
delete require ‘tempfile’ … if the program still runs fine then ur  
gold.
