Odd, now that I try it, each *is* faster than for. I'm going to have to 
investigate.

JRuby:
                      user     system      total        real
for loop         0.334000   0.000000   0.334000 (  0.334033)
each             0.236000   0.000000   0.236000 (  0.235695)

Ruby 1.8.6:
                      user     system      total        real
for loop         1.050000   0.010000   1.060000 (  1.079704)
each             0.950000   0.010000   0.960000 (  0.982576)

Ruby 1.9:
                      user     system      total        real
for loop         0.910000   0.010000   0.920000 (  0.933510)
each             0.420000   0.000000   0.420000 (  0.431548)
