<pre>The test checks that the object fits into ram (run with --debug to verify that
the size is indeed valid). It is probable that the huge-cpu would also fail
given enough time to allocate the full object. But it's the spurious oom that
kills us:
[ 100.627668] 0 pages in swap cache
[ 100.627670] Swap cache stats: add 550, delete 550, find 0/0
[ 100.627671] Free swap = 1950564kB
[ 100.627673] Total swap = 1952764kB
[ 100.627674] 1028502 pages RAM
Why are we not pushing others out to swap in get_pages_gtt()?</pre>
