In the past badsignal would crash the program. In https://golang.org/cl/10757044 badsignal was changed to call sigsend, to fix issue #3250. The effect of this was that when a non-Go thread received a signal, and os/signal.Notify was not being used to check for occurrences of the signal, the signal was ignored. This changes the code so that if os/signal.Notify is not being used, then the signal handler is reset to what it was, and the signal is raised again. This lets non-Go threads handle the signal as they wish. In particular, it means that a segmentation violation in a non-Go thread will ordinarily crash the process, as it should. Fixes #10139. Update #11794.
