Bug Description
Utah is being used to run tests like smem that are memory sensitive. We could exclude utah from showing up in the smem results, but that might not be enough. The fact that utah does consume a large amount of memory could cause other effects that are not good during these types of tests.
From Colin King:
My concern is that overall, UTAH is consuming quite a large proportion of overall memory, so this adds to the virtual memory "pressure" than can lead to dirty pages being flushed out earlier and unused pages being push out of physical memory. This leads to a skewing of the RSS and PSS stats.
Can anything be done to dramatically reduce the memory footprint of utah?

As an example, on http:// ci.ubuntu. com/memory/ idle/arch/ amd64/machine/ 2/install/ result/ 19465/details/ we see utah using about 76M
