+Subject: [PATCH 7/7] abort: raise SIGABRT again if signal is ignored
+
+POSIX requires that abort() gives the SIGABRT status to waitpid(3) and
+friends. If a signal handler is installed, and erroneously returns,
+then the status given to waitpid(3) is SIGSEGV instead of SIGABRT.
+
+This change gives another opportunity for the proper SIGABRT status to
+be given to any process monitoring this one's process, before we fall
+back to a_crash(), which should be sufficient.
