Linux scrubs memory before returnign it to Xen, or transferring it to
other domains (e.g., net backend driver). To avoid continual scrubbing during
network transfers, I allocate rx skbuffs from a dedicated slab cache. Pages
only neded to be scrubbed on entry to the cache, which should be ratehr more
occasional than allocs/frees.
Finally, scrubbing can be entirely disabled via a config option under the
'XEN' menu in the 2.4 and 2.6 kernel configurators.
