question about delayed ACKs on OpenBSD

Hello I've noticed a bit different behaviour with regard to delayed acks on OBSD. Some other systems (2 linux distros, win2k/xp) I tested, pretty much acted as I've always seen it - 1 ack per max. 2 segments, but no bigger delay than some arbitrary value (looking at rfc, no more than 500ms,
