> Resource arithmetic concerning += and -= operators needs to be improved such that the
impact of shared resources is minimal. Following is the observation of Resources_BENCHMARK_Test.Arithmetic.

> 'total += r' run time sees 40% jump. (I've run these 10 times and took an average, the
avg is 48685.4us (pre-shared resources) vs. 68421.7us (post-shared resources).
