What steps will reproduce the problem?
1. Schedule tests for 2500 nameservers
2. Wait..
3. Wait...

What is the expected output? What do you see instead?

I expect it to finish, but it gets stuck on the final one. Perhaps an external 
timer would be nice.

Please see Issue 219 for the Mountain Lion issue with wildcard cache queries.

Got it. Checking on the solution now. 

Change this file: namebench.app/Contents/Resources/libnamebench/health_checks.py
Old line 203: "hostname = 'namebench%s.%s' % (random.randint(1, 2**32), domain)"
New line 203: "hostname = 'namebench%s.%s' % (random.randint(1, 2**16), domain)"

That line change seemed to do the trick. Working well now.
