Noting the recent conversation on integer arithmetic in Erlang, I tested 
my random_mt module on my 32-bit Athlon machine and it performed 
somewhat worse than stdlib:random, similar to the reported performance 
of the MT implementation I linked in my previous post on this thread. So 
I guess my hubris was a little unwarranted as most of my improvements in 
performance came from running it on a 64-bit machine. :)
