	The differences are almost certainly in the resolver library, not 
the server.  Try running the test under "truss", "ktrace", "strace", 
or other system/library call tracking packages, and they might be 
able to give you some more detailed information as to exactly what is 
going on and where.

	Also, the OS version you're running under might make a difference 
(e.g., Apple seriously broke the resolver code when they added some 
proprietary multicast DNS stuff, and they have not yet fixed what 
they broke in the process).  Did you provide this information 
previously?
