Ugh, yes, this is tricky to test...
Does the following help?

diff --git a/test/test_poll.rb b/test/test_poll.rb
index d9a2b07..5c8071d 100644
--- a/test/test_poll.rb
+++ b/test/test_poll.rb
@@ -108,6 +108,8 @@ class TestPoll < Test::Unit::TestCase
     assert_equal({@wr => Kgio::POLLOUT}, res)

     assert ok
+
+    1000.times { Thread.pass } # let signal handlers fire
     ensure
       trap(:USR1, orig)
   end


(I'm sleepy myself and thinking out loud)
Or it could be just made to sleep (and slow down the tests even more)
Thanks!
