lol.  I imagine he doesn't want to get swatted by ruby purists.  He
compiled into machine code instead of using the interpreter?

For what it's worth, I was able to have an 800MHz machine do 30
seconds with the 1.8.6 standard build from source by disabling the GC
in irb and loading via...

irb> load "test.rb"

Standard time during normal computer operation for executing the OP's
code was around 49+/-5 seconds.  Normal operation included having a
heavy use network session mixed with X Windows open and a window
manager.

I pushed it to do less than 20 seconds by rewriting the code
(cheating) to omit the inject method, making it look ugly with while
loops, and also leaving out the puts/p/print methods.

I will confirm that it was extremely easy to beat the one-click
install on a newer/faster Windows machine with 1.8.6.  Nothing against
that, though, because making a clean install of anything on Windows is
nothing less than an act of God (nothing against the Windows fans
either; it justs seems harder than it needs to be; I think this will
change eventually).  I have yet to attempt Cygwin or MingW building on
a Windows system, though.  I haven't tried the 1.9 installer yet,
either.
