Has there been a modification of some APIs in Mac OS X 10.3.9 that could explain why Mail.app and Safari.app hang (2 minutes to complete launch on a fast G5) in the [NSHost currentHost] call when you launch them for the first time?

As this Cocoa API potentially deals with network related stuff, I wonder if a bug would not have been introduced in a security update for 10.3.9 as I've not seen this problem previously.
I don't believe we touched the NSHost code at all for any security update.
[snipping the sample a bit]
983 -[NetworkController domainName] 983 +[NSHost currentHost] 983 getnameinfo 983 _lookup_all 983 _lookup_all_secure 983 mach_msg 983 mach_msg_trap 983 mach_msg_trap
This indicates that getnameinfo is going off to talk to lookupd - what does it look like lookupd is doing?

From what I experienced, this kind of slowdown can be caused by a DNS being down, very busy or the DNS address being incorrectly set.

It looks strange from an user point of view that an application is taking a long time to start for this reason (with no further explanation).
