While the 64-bit builds can use more than 2GB of memory, it's true for 
the overall memory usage only. But the page cache size is limited by 
128K pages (512MB-2GB, depending on the page size). It's not a problem 
for Classic, but it's going to bite you if you're using SuperServer.

I think we should increase the limit, at least for the 64-bit builds. 
Objections anyone?
