s/GpuAccessAllowed/GetWindowCount/, I think.

Yes...
If you get a chance, please double-check that you have meaningful data there in
case of GPU process crash recovery, e.g. by killing it.

Bork Bork. I rushed and get messed up autocomplete.

I've put the right call in and in a test program added a printf() in the
GPUMemoryManager and confirmed it received the right number of windows after I
killed the gpu process.
