typo. * test/-ext-/old_thread_select/test_old_thread_select.rb (TestOldThreadSelect#test_old_select_signal_safe): use SIGINT instead of SIGUSR1 because the former is general and the latter is platform dependent. git-svn-id: svn+ssh://ci.ruby-lang.org/ruby/trunk@33130 b2dd03c8-39d4-4d8f-98ff-823fe69b080e
