Subject: Strange behavior connecting to non-listening TCP ports

With my previous kernel, NetBSD/alpha 1.4S from Feb 16, telnetting to a
port that didn't have anyone listening would (eventually) give me a
Connection timed out message, rather than Connection refused.
I've now upgraded to 1.4T from Feb 18, and I get this:
yerfable ~> telnet localhost 1234
telnet: connect to address 127.0.0.1: Connection refused
telnet: Unable to connect to remote host: Connection refused
with the first 3 lines printing immediately, and the last line printing
after an ~6 second pause. "telnet yefable 1234" works as expected though
(connection refused immediately).
So what's with the two attempts to connect to localhost, and why the
long pause? I don't have ipfilter in my kernel, and don't think I've
changed anything in my kernel config recently.
