It actually ended up being my own stupidity.  I finally had time to
finish testing the last change, back to no "set nexthop" in bgpd.conf.

For the archives, what caused the issue was me trying to do something
fancy.  I had multiple routes to the same networks and I set those up
with ifconfig -mpath.  Kernel multipath does not yet work, and it really
confused bgpd.  With the multiple routes to the same networks removed,
everything works as expected and OpenBGPd has made me very happy!

Now all I have to do is finish my migration from eigrp to ospf so I can
get rid of the static routes on my OpenBSD routers and all will be good.
