Ah, I see.  I believe Eric was originally asking you to enter only this 
command:
   ruby -rsocket -e 'p Socket.gethostbyname("127.0.0.1")'

which should (and apparently does) print:
   ["localhost", ["test"], 2, "\177\000\000\001"]

to the console.  The section "\177\000\000\001" is the binary 
representation of the IP address that the gethostbyname system call 
actually used (I think - slightly outside my area), and if it had been 
different it would have indicated DNS or low-level IP weirdery.  I think.

If you remove it (set RUBYOPT=""), does the time taken to run your 
counting script improve?  I can't think of any reason that it should 
(barring AV-scanning of opened files), but it might narrow the scope a 
little.
