What you believe the man pages?

in /usr/src/sys/net/netinet/tcp_usrreq.c

tcp_usr_accept(

..
if (so->so_state & SS_ISDISCONNECTED)
   error = ECONNABORTED
...

The notes I've seen imply the socket can get disconnected somewhere 
between the connect, and the accept. So a somewhat new FREEBSD 
behavior is to throw the ECONNABORTED.

Ah the OpenBSD code is quite different, unable to understand how it 
terminates early quite yet.

Well I didn't check, but does it imply the waitforconnection will 
terminate right away or do we wait for the timeout? Then again I 
didn't notice any pauses so is that ECONNABORTED connection just 
ignored? (yes I think)

I'll await your code. Sometime in the next 24 hours I'll review all 
the signaling to understand how/what/where
