+ * Handle a fatal signal by launching a debugger, controlled by $RSYNC_PANIC_ACTION.
+ *
+ * This signal handler is only installed if we were configured with
+ * --enable-maintainer-mode.  Perhaps it should always be on and we
+ * should just look at the environment variable, but I'm a bit leery
+ * of a signal sending us into a busy loop.
