?? Perhaps you're assuming the wrapper in _cpwsgi is being proposed, but
it isn't. That has all of the CherryPy-specific "stuff" in it. The base
file (_cpwsgiserver) has no dependencies except for stdlib modules.

These are not present in the base _cpwsgiserver.

Okay, now you're really looking in the wrong place. Ignore
_cphttpserver; it's deprecated and has nothing to do with WSGI. Look at
_cpwsgiserver and only _cpwsgiserver.

Look at the right code and see if your gut feeling changes. ;)
