And "with enough registers" includes ARM and MIPS, right?  So the only
real problem is 32-bit x86, and you're right, at that point, only
people who might care are people who are using a space-radiation
hardened 386 --- and they're not likely to be doing high throughput
TCP connections.  :-)

Plus the benchmark was bogus anyway, and when I built a more specific
harness -- actually comparing the TCP sequence number functions --
SipHash was faster than MD5, even on register starved x86. So I think
we're fine and this chapter of the discussion can come to a close, in
order to move on to more interesting things.
