  New Revision: 64993

  https://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=revision&revision=64993

  Log:
    spec/.../ole_method.rb: retry WIN32OLERuntimeError
    
    This part sometimes causes random failure like:
    https://ci.appveyor.com/project/ruby/ruby/builds/19382723/job/bedc33p4nolcqkp6
    
    Let me retry this to make CI stable.
