However, calling gem_quiescent_gpu() inside get_object_count() is probably overkill, and could potentially mask something going wrong (not so much when called at the beginning of a subtest, but definitely when called at the end!).

Well i-g-t testcase run under the assumption that nothing else does,
so most often the drop_cache call would be a noop. Save when there's
indeed something left to retire, in which case it matters actually.
I'll add it if you don't feel like doing it yourself.
