The next changeset from Joyent (Jerry Jelinek, this time) focusses on
false-sharing in the TCP stack, and raising some default fanout values:

I also have no problem with these set of changes.

I will WARN folks that there are other such closely-placed locks in the
TCP/IP code.  Off the top of my head:

	- connf_t (ipclassifier.h)

	- irb_t  (ip.h)

	- isaf_t  (sadb.h)

If anyone has a high-stress networking test rig (Hello Joyent?), please
contact me here or off-list so we can talk about these other sources of
false-sharing.

Again, please speak up so this changeset can go back!

Thanks,
Dan
