Under FreeBSD you could try the following:-

 1) run ALTQ on the loopback interface and prioritize control plane traffic
    passing through the IP stack at the expense of data plane traffic;

 2) use a different underlying IPC mechanism for the control plane traffic,
    e.g. POSIX message queues.

That's all I can think off of the top of my head right now...
