Well, yea, but I'd rather have a blocking kldload than a panic'ed 
system.  There are probably more such places.  Actually I think this 
limit business is stupid.  Rather than panicing, we could print a 
warning and go on.  The worst thing could be that we'll panic lateron 
because we don't have free memory anymore.
