Is wsgi ready for prime time?

[Ron Garret]

The wsgiref module in Python 2.5 seems to be empty:

[ron at mickey:~/Sites/modpy]$ python
Python 2.5 (r25:51908, Mar  1 2007, 10:09:05) 
[GCC 4.0.1 (Apple Computer, Inc. build 5367)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import wsgiref
>>> dir(wsgiref)
['__builtins__', '__doc__', '__file__', '__name__', '__path__']
>>> 

So... is wsgi considered ready for production use, or is it still on the 
bleeding edge?  And if the former, which implementation should one use?
