It could. If there are timing sensitivities to this issue then it might
be sufficiently perturbed that it doesn't reproduce. The above backtracing
is expensive and increases the performance impact. However, given that
we want to know who the caller was and determine the source of the 4.2GiB
allocations... we need to try capture that information.
