    * lib/test/unit/parallel.rb: fix test-all parallel failure if a test
      is skipped after raise.
      DL::TestFunc#test_sinf is skipped after raise on mingw ruby.
      But it causes Mashal.load failure due to undefined class/module
      DL::DLError when doing test-all parallel and test-all doesn't
      complete. We create new MiniTest::Skip object to avoid Mashal.load
      failure.

    * test/testunit/test_parallel.rb (TestParallel): add a test.

    * test/testunit/tests_for_parallel/ptest_forth.rb: ditto.
      But it causes Marshal.load failure due to undefined class/module
      complete. We create new MiniTest::Skip object to avoid Marshal.load
