  New Revision: 65383

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=65383

  Log:
    test_io.rb: skip busy wait test again
    
    which I tried to avoid skipping this in r65311, but the test seems not
    working under some high load of ci.rvm.jp.

  Modified files:
    trunk/test/ruby/test_io.rb
