Careful here. If your box is running several Gig Ethernet interfaces,
it could well be allocating 100s of MB of skbuffs every second, each
allocation being very short-lived. The rate of allocation is not a
good indicator of memory load. The rate of allocations which could
not be satisfied immediately would be a far better metric.
