If you search cco for "tcp intercept", you should find
something interesting. This feature was available in
11.2(4)F. ((paraphrased from memory))
Basically the router completed the handshaking then passed
on the completed connection to the inside host.
When under attack, it halves the timeouts (progressively?)
for half-open connections.
I don't know what happened to the F branch. It seems to have
been left behind.
