If you've just booted up and there is a one in a few million chance
that you'll get half way on the database load on the first adjacency
to come up and have to start over, then I don't think it is a big
deal.

If the point is what if you've been up and running for a while, then
perhaps we need a holdup timer to see if the problem clear if one or
more adjacencies has previously completed a full database load.  This
means that on a power up of everything, there will be merged islands
with conflicts and the conflicts won't resolve until the holdup timer
expires.  Some advice on being slow to correct "staleness" in this
situation would prevent the current OSPF staleness correction wars
(each corrects the other as fast as it can if you manage to configure
a conflict today - apparently common when people clone and edit
configs but occasionally forget to change the router-id - I wouldn't
know since we machine generated the configs where I used to play).
