Takes around 30s to run the exercise on my i3. The fun part is that it
tries to allocate 3+ GiB of memory in order to cause the aperture
thrashing and so test evicting tiled buffers. If you don't have that much
memory available, then you get swap thrashing or even the dreaded OOM.

[I thought about limiting it to total available memory...]

Is your machine making any progress? Did the kernel send any warnings over
netconsole? How much memory do you have and what is your timeout?
