I honestly hope that GL_AMD_pinned_memory doesn't become popular. It would have been alright if it wasn't for this bit in http://www.opengl.org/registry/specs/AMD/pinned_memory.txt which says:2) Can the application still use the buffer using the CPU address? RESOLVED: YES. However, this access would be completely non synchronized to the OpenGL pipeline, unless explicit synchronization is being used (for example, through glFinish or by using sync objects). And I'm imagining apps which are streaming vertex data doing precisely just that...
I don't understand your concern, this is exactly the same behavior GL_MAP_UNSYCHRONIZED_BIT has, and apps are supposedly using that properly. How does apitrace handle it?
