umm.. I've never seen any numbers from you, David.

I'll work on something for you this week then :-)
Not a problem.

ergo, there is no point in futzing with the pagecache_lock *at all*
until either TUX is merged, or we decide to support large-scale
NUMA hardware well

Or your "1a", "other sendfile applications", right?

I really still feel (and will try to show with numbers) that the copy
being present is not so important. Like I have stated on other
occaisions, several platforms do not harm L2 cache state during
copies, new lines are never brought in.

I expect x86 systems to move more in this direction if they aren't
somewhat there already.
