After seeing some of the ideas regarding how to add async into a new
version of WSGI, it isn't the specific problem the async feature
addresses in terms of WSGI servers. Is the goal is to support long
running connections? Are we trying to support WebSockets and other
long running connection interfaces? If that is the case, async is a
*technique* for handling this paradigm, but it doesn't address the
real problem. There are techniques that have sounded reasonable like
making available the socket such that a server can give it to the
application to do something use with it (here is an example doing
something similar with CherryPy - http://trac.defuze.org/browser/oss/ws4cp/ws4cp.py).

Just to summarize, I'm for making async something else while finding a
way to support long running connections in WSGI outside of adopting a
particular technique a potentially viable goal.

Just my $.02 on the issue.
