Ugly waitpid_core_once :(

waitpid_core_once.c

pid_t waitpid_core_once(pid_t pid, int *status, int options)
{
        int status_holder;
        pid_t retval;
        if (!status)
                status = &status_holder;
        retval = waitpid(pid, status, options);
        if (retval > 0 && WIFSIGNALED(*status) && WCOREDUMP(*status)) {
                struct rlimit core;
                memset(&core, 0xFF, sizeof(core));
                if (getrlimit(RLIMIT_CORE, &core) == -1)
                    uwsgi_error("getrlimit(RLIMIT_CORE)");
                uwsgi_log("DAMN! pid: %d was killed by signal (%d) and dumped core, limits are {soft: 0x%x, hard: 0x%x}, disabling further core dumps to avoid flood...\n",
                        retval, WTERMSIG(*status), core.rlim_cur, core.rlim_max);
                core.rlim_cur = 0;
                if (setrlimit(RLIMIT_CORE, &core) == -1)
                    uwsgi_error("setrlimit(RLIMIT_CORE)");
        }
        return retval;
