Right.  I would suggest that iconForPageURL should always return 0 unless and 
until readIconForPageURLFromDisk is called which actually triggers the load. 

It should be noted that *nothing* currently uses 
readIconForPageURLFromDisk() ;)

I guess I just couldn't believe that Safari calls iconForPageURL twice.  It is 
very unclear API.
