 Here's the timings for a relatively simple program.

 (Caveat: Yes, it's using regular expressions to parse HTML; it's a stop-
 gap until I can make Nokogiri work with MacRuby in an app bundle.  The
 point, however, is that partitioning, or some other operation done by this
 code, is somehow a _lot_ slower in MacRuby.)

 The outputs are as follows:

 {{{
 $ rvm system --verbose
 Now using system ruby.
 $ ruby --version
 ruby 1.8.7 (2009-06-12 patchlevel 174) [universal-darwin10.0]
 $ ruby parse_html.rb
 Just partitioning took: 0.0182089805603027
 Number of partitioned splits: 2400
 $ rvm 1.9.2 --verbose
 Using /Users/mrs/.rvm/gems/ruby-1.9.2-p136
 $ ruby parse_html.rb
 Just partitioning took: 0.033324480056762695
 Number of partitioned splits: 2400
 $ macruby parse_html.rb
 Just partitioning took: 1.19672107696533
 Number of partitioned splits: 2400
 $ macruby --version
 MacRuby 0.8 (ruby 1.9.2) [universal-darwin10.0, x86_64]
 }}}

 Attached is a zip file with the HTML being parsed, and the tiny Ruby
 program that's doing it.
