Nobu, could you review the patch? And if you don't see any problem, check it in?

Bug #6183: Enumerator::Lazy performance issue
https://bugs.ruby-lang.org/issues/6183#change-25631
Author: gregolsen (Innokenty Mikhailov)
Status: Assigned
Priority: Low
Assignee: nobu (Nobuyoshi Nakada)
Category:
Target version:
ruby -v: ruby 2.0.0dev (2012-03-17 trunk 35075) [x86_64-linux]
I benchmarked Enumerator::Lazy and that's what I got:
user system total real
Lazy: 0.690000 0.010000 0.700000 ( 0.733160)
Normal: 0.160000 0.010000 0.170000 ( 0.186695)
It seems like even with 4 chain links and 3000 elements in initial array, Lazy enumerator is almost 4(!) times slower than the normal case.
Instead of performance benefit we've got 4 times performance drawback.
See test file attached.
