Does 'for' reevaluate its range after each tick? That would give 'for' a single 
technical advantage over .each, in the very rare chance you need that.

Otherwise, where does the time go?

A quick experiment with RubyNode just showed Ruby generates different opcodes 
for 'each' and 'for'. (By contrast, the notorious ternary operator, ? :, 
generates the same opcodes as an equivalent 'if then else end' construction.)
