Bug #4439: TestBeginEndBlock#test_should_propagate_signaled が必ず1度失敗する
http://redmine.ruby-lang.org/issues/4439

Author: Motohiro KOSAKI
Status: Assigned
Priority: Low

% make test-all TESTS="-v  test/ruby/test_beginendblock.rb -j2"

のように、test_beginendblock.rbを並列実行すると

のように test_should_propagate_signaled が必ず1度失敗してから
リトライで成功します。
