Is there a performance test that demonstrates an advantage to this change?

Just knowing that a system is low on physical memory is not sufficient cause to garbage collect. At the limit, you would garbage collect after every byte allocated, which is O(n^2). I don't think that's a good idea.

Perhaps we could incorporate system load when calculating m_bytesAllocatedLimit. I could make a clearer suggestion if I knew more about the problem you were trying to solve.
