Mozilla behaving strangely today

[walt]

Just built quickworld/kernel (0600 June 8) and I'm seeing a bizarre
problem with mozilla:
Any URL I type in will hang forever on the 'resolving address...' step.
If I type in the IP address, however, it all works normally.
I also had to change the 'nntp.dragonflybsd.org' server name to its
IP address in order to post this.
No other application seems to be affected by this -- my local nameserver
is working fine -- all other apps can use it.
I noticed lots of changes to libc this morning -- I wonder if that has
anything to do with this.
I'll try recompiling mozilla to see if that fixes it, but I was curious
if anyone else is seeing the same thing.
