bird doesn't re-evaluate, but this can be worked around in a non-ideal way:

> 40 11,20 * * * root /usr/sbin/birdc -s /var/run/bird/bird-rs1-lan1-ipv4.ctl reload in all >/dev/null

~100 clients causes CPU spikes as shown in the graph below.

The decay profile in the spikes is caused by reloads of other bird 
instances on the same vm.
