Regarding the above comment.

 

Drivers are free to swap your buffers from RAM to video RAM (VRAM has two meanings in this context) and the other way around at any point of time.

While giving them hints as to the usage of buffers might (and again, might not) make them initialize the buffer where you want, drivers are free to do real-time analysis as to the actual usage of your buffers, and swap them if they want to, and in fact I read years ago that they indeed do this.
