void qtest_quit(QTestState *s)
{
     int status;

     if (s->qemu_pid != -1) {
         kill(s->qemu_pid, SIGTERM);
         waitpid(s->qemu_pid, &status, 0);
     }

     close(s->fd);
     close(s->qmp_fd);
     g_string_free(s->rx, true);
     g_free(s);
}

Not async-signal safe.  You need to ignore the g_string_free and g_free 
(perhaps even the closes) if calling from the sigabrt_handler.
