This test exercise purely to exercise the shrinker under some common
stress (i.e. paths leading to i915_gem_object_get_pages()). We try to
fill the entirely of memory split amongst many processes so that each
individual process only consumes a small fraction of RAM (less than the
mappable aperture) and a single process should not be individually
blamed.
Based on an idea to have a seperate set of memory stress tests by Piotr
Luc.
