While startup speedup improvement is relatively small compared current implementation, this one does not need any Ruby Objects at all, so that there is no presure on GC. https://github.com/ruby/ruby/pull/264.patch https://github.com/ruby/ruby/pull/264.diff https://github.com/ruby/ruby/pull/264 -- http://bugs.ruby-lang.org/
