Yes, I think that is an issue.  48 flags may sound like a lot, but the 
existing 8 flags got used up fairly quickly and suddenly; one draft 
grabbed four flag bits.  So FCFS doesn't really seem like an appropriate 
policy here.   The other possible policies are all subject to politics, 
but at least Standards Action comes with early allocation.
