Currently, we're only applying this max check to CompleteSubspace::tryAllocateSlow. We found that adding it to LocalAllocator::allocateSlowCase can cause crashes due to failed Structure allocations (which are fatal). As a result, the testing disruption from those crashes far outweigh any benefits we currently get from it. So, we'll leave the max check out of LocalAllocator::allocateSlowCase for now.
