 Test Script:
 {{{
 #!ruby
 $ cat test_load.rb
 COUNT = 5
 FILE  = "tmp-load-test.rb"

 open(FILE, "w") {|f|
   f.puts "module TEST"
   f.puts "end"
 }

 val = (1..COUNT).map {|i|
   Thread.start {
     load "./#{FILE}"
     TEST
   }
 }.map {|t| t.value }

 COUNT.times do |i|
   p val[i] == TEST ? :ok : :ng;
 end
 }}}

 Result of Ruby 1.9.1:
 {{{
 $ ruby test_load.rb
 :ok
 :ok
 :ok
 :ok
 :ok
 }}}

 Result of MacRuby Trunk:
 {{{

 Sometimes, Test Script succeeds to run.
