The following demonstrates that Thread#wakeup can be used in a signal trap to wake up the thread that had control when the signal was raised. I have verified same behaviour in MRI (1.8.7, 1.9.3, 2.0.1, 2.1.1), JRuby (1.7.4, 1.9 mode), Rubinius (2.2.1), but testing signals is hard and I'm unsure how to verify this programatically.
