  New Revision: 29281

  http://svn.ruby-lang.org/cgi-bin/viewvc.cgi?view=rev&revision=29281

  Log:
    * test/io/console/test_io_console.rb (TestIO_Console::helper):
      PTY.open is not guaranteed to work.  On my machine opening a
      pty is prohibited via process control group.  On those cases
      exceptions shall occur, and that doesn't mean our fault.
      Skip those tests on such situations.
