Hi, Joe,

Huh? I don't follow this. Could you clarify what's the "extra state" and
"extra processing" you're referring to?

Joe, please read the I-D. It's *without* this RFC1948-like scheme that
timeouts/delays could occur. -- this mod actually improves the handling
of incoming connection requests (SYNs), allowing connections that would
have otherwise failed.

(see also the reference to Mike Silbersack's presentation at BSDCan)

Thanks,
