 Test Script:
 {{{
 #!ruby
 $ cat test_thread_kill.rb
 Thread.new {
   i = 0
   loop do
     p i
     i += 1
     sleep 0.5
   end
 }

 sleep 3
 Thread.main.kill

 p "ng"
 }}}

 Result of Ruby 1.9.1:
 {{{
 $ ruby test_thread_kill.rb
 0
 1
 2
 3
 4
 5
 }}}

 Result of MacRuby Trunk:
 {{{
 $ macruby test_thread_kill.rb
 0
 1
 2
 3
 4
 5
 uncaught Objective-C/C++ exception...
 terminate called after throwing an instance of
 'RoxorThreadRaiseException*'
 zsh: abort      macruby test_thread_kill.rb
 }}}

 I think that MacRuby should calls rb_exit() when kills the MainThread.
