The offending code in src/sbin/routed/if.c:
        for (;;) {
                if ((needed = sysctl_buf_size) != 0) {
line 717 --->>          if (sysctl(mib, 6, sysctl_buf,&needed, 0, 0) >= 0)
                                break;
                        /* retry if the table grew */
                        if (errno != ENOMEM && errno != EFAULT)
                                BADERR(1, "ifinit: sysctl(RT_IFLIST)");
                        free(sysctl_buf);
                        needed = 0;
                }
                if (sysctl(mib, 6, 0, &needed, 0, 0) < 0)
                        BADERR(1,"ifinit: sysctl(RT_IFLIST) estimate");
                sysctl_buf = rtmalloc(sysctl_buf_size = needed,
                                      "ifinit sysctl");
        }

It appears that routed is getting stuck in a buzz loop here.
This happens even without aliases on an interface.  I have only
three interfaces, epic0, wi0, and ppp0, and none of them have an
alias.  I believe this happens regardless of whether the ppp0 changes
state or not.

Any ideas here?  Is a 'for (;;)' the best thing here?
