Flutterby™! :

My how far we've come. I've now seen a real world application which is crashing because something (we're not yet sure what) is using signed 32 bit integers to keep track of memory, which is exceeding two gigabytes. And we're getting nervous about only having 32 bit pointers in our application. I'll let that sink in for a moment. A running application using 4 gigabytes of data. Choke. It was only a short time ago when we thought that was a big database. It's funny to hear OS and hardware vendors revise terms in year or two old documents which refer to this as "essentially unlimited."
