---------------------------------------------------------------------- 
I applied the patch to 1.6.2.3-rc2, although patch REALLY didn't want to
apply the dnsmgr.c changes for some reason, so I applied them by hand.  I
don't see why it didn't want to apply them as the line numbers were right
and everything looked the same to me.  The other two files patched just
fine.

It's only been running for about 3 hours with the patches, but I haven't
seen any problems, yet (and I definitely would have seen problems by now
without the patches if I didn't have callcentric.com hard coded in my local
DNS - I took out the hardcoded address for this test).

I'll let you know if I see any problems.
