Same environ cannot be used twice for WikkidApp

[Sam Bailey]

After an environ has already had its path_info shifted in WikkidApp.preprocess_environ, it will get stuck inside the while loop if that same environ is then sent back into preprocess_environ.
For example, calling

app.get_view(environ)
app(environ, self.start_response)

will result in an infinite loop.

Yes...

I'm wondering if the wsgi spec allows copying of the environ.

Why are you doing this anyway?

I'm no longer using that specific example.

I am still calling preprocess_environ on the environ though in order to get a path, which is then used to determine if I send the request to the WikkidApp or carry on and get a view for it, both of which end up using that environ again.

As a temporary fix, yes I was copying the environ. It seems there should be a nicer way though
