hi carl / arigo,
could i ask of a quick favour?
i'm interested in the performance of :
   1000000000.times {
     d = d + 1
   puts d
as in, just a loop that goes from d=0 to d=1000000000 and prints d out 
at the end.
for some stupid reason a few people have decided to benchmark
this with mono and ruby and i wanted to show them the
llvm and psyco results so they could weep ;)
