A bit of history:

In the earliest days of TCP design (1973-1974), we worked very
hard to make sure that self-simul-syn would work (sounds vaguely
self-abusive, doesn't it?).

Richard Karp (not the one at Berkeley, but the one now running
Reliable systems in Palo Alto) was a graduate student working
on one of the first TCP programs (in BCPL). We assured him that
the design really was intended to work on a self-connect but
I recall his astonishment when we tried it and it, indeed, worked
just as advertised.
