Also, wsgi_lite provides a way of registering resources to be closed
post-response, that works within WSGI 1.0, also without altering the
returned iterable:

  https://bitbucket.org/pje/wsgi_lite#close-and-resource-cleanups

Although wsgi_lite provides programmatic support for this, it's
internally implemented as a stock WSGI extension key
('wsgi_lite.closing') in the environ, and can be offered today by
servers or middleware in a 1.0 environment.  I just haven't gotten
around to knocking out a PEP for it.
