I took a wild guess that gethostbyaddr() was failing and seems it was right.

Not sure why the Subversion server *must* suddenly be able to
gethostbyaddr() on the client's IP address with 1.3.0. My guess is
that SSPI uses Kerberos - Kerberos always has been picky with host
names (and wall clock time) and such.

gethostbyaddr() apparently first checks the hosts file, then tries to
find a PTR record in DNS and then it starts broadcasting over NetBIOS.
 The NetBIOS thing has a ~1 sec timeout and it tries 3 times, which is
where the ~5 second delay comes from.

There's obviously a bug somewhere, since it broadcasts for a workstation named
*<00><00><00><00><00><00><00><00><00><00><00><00><00><00><00>. Had it
done a broadcast for my workstation's real name then it would've
gotten a correct answer in a splitsecond.

Hrm. Well, hope someone who knows more will hunt that one down some
day. For now I've worked around the problem by patching our DNS.

I'd hate to be the next user to have that error message shoved in my face ^_^.
