I just installed 2.2.0alpha1 onto an NT machine that already had two copies of Zope running happily on it. The new copy of Zope refuses to start with the following traceback: Traceback (innermost last): File "<stdin>", line 1, in ? File "z2.py", line 524, in ? import ZServer File "D:\zope2\ZServer\__init__.py", line 123, in ? from HTTPServer import zhttp_server, zhttp_handler File "D:\zope2\ZServer\HTTPServer.py", line 116, in ? from HTTPResponse import make_response File "D:\zope2\ZServer\HTTPResponse.py", line 97, in ? from PubCore.ZEvent import Wakeup File "D:\zope2\ZServer\PubCore\ZEvent.py", line 91, in ?

Zope 2.1.6 had this code inside a loop so that if the bind failed it subtracted 1 from the port number and then tried again until it found a free port (or gave up after trying 50), but the loop has been removed in the new release.
