I tried to get pages added at the US Embassy in Beirut a few days ago, getting there a trip in and of itself, but they said they wouldn't go beyond three additions, which I already had, and that they needed one day to do it anyways. Shucks...
I stopped a fellow United Statesian in Doha Airport and he had quite the tome of a passport. I asked him what the deal was with his seven additions, and he said go to one you've been to already in order to get them to go beyond the "limit of three." So I went to the consulate in Hong Kong, and sure enough, since my passport was in copacetic condition, fifteen minutes later I was set. Of course, it could just depend on whom you are speaking with, but I reckon each embassy/consulate could have its own deal.
