A WSGI middleware app is simply a callable thing that calls the next
app, so the overhead is literally the same as a simple function call.
There won't be security proxies or any other such thing getting in the way.

The current publisher is chock full of function calls and adapter
lookups along the critical path. I expect the zope.pipeline project to
open everyone's eyes about just how much we're already doing in the
critical path. I think much of it is frequently not needed at all.
