under windows xp, rc2 fails to execute the test suite. rc1 works fine ====================================================================== ERROR: test_1_Restart (test_states.ServerStateTests?)

Probably caused by some network setup problem on this perticular computer

- milestone changed from 2.1-rc2 to 2.1-final.
I did some investigation... Test suite runs fine if test_states is not run. All state tests run fine for the serverless state tests. wsgi state tests run fine if restart test is not run. Only the normal flow state test works for the the pooled thread server state test. For the http server, again, restart throws in the towel.
As far as i can tell, the issue isn't a network problem, but a threading problem. The above error occurs because the port is never freed, and thus is in use, and fails to be rebound. I have carefully tested quite a few other networking apps, without incident.
I believe that these errors become apparent on my development system, as I am using a dual core pentium IV. Multiple processors on a particular os can often expose threading issues that don't occur on single processor systems, or on multi processor systems with other another os.
Please test again with a dual core system xp system. Thanks!

I have the Pentium IV dual core and cannot run the simple helloworld.py tutorial with CherryPy 2.3.0

Addendum... all of the tutorials do, however execute without problem
