For PHP their may not be a strict entry point like with WSGI, with instead the script itself effectively being in the inner port of the application entry point, but you still need to deal with an API of sorts within it when dealing with response at least. If not, can't set headers or override response status. http://au2.php.net/header >> The daemon mode in mod_wsgi is a part solution to this, but as it is >> now, it requires WSGIDaemonProcess/WSGIProcessGroup for each user to >> be set up and configured.

It would never have been back ported anyway. 1.X and 2.X streams only get bug fixes with the way I treat release numbers. New features only go in major versions. Whether it gets done in version 3.0 comes down to time. Even with my baby being almost 1 year old, my time to work on mod_wsgi is still very constrained and one needs a lot of head space to work on something like the transient daemon process feature. > I'm not just talking about simple code embeds like this.

Users don't have to concern themselves with the setup only because the hosting provider made a prior decision to host PHP code and set it up. If the hosting provider decided that hosting Python was also a good idea and had similarly done the required setup just like they had for PHP, then again wouldn't be something that the user would have to worry about. Now we may not have all the building blocks in place just yet, but there is no reason why a similar positive experience can't be had by Python developers. Just look at Google App Engine as an example. There is no reason why one couldn't do something similar with Apache as a base. If daemon processes are used, if uploads are mediated through a web application then as a side effect it can touch the WSGI script file to enact the necessary restart of application. Thus it all comes down to the solution around the hosting mechanism for managing it and interacting with it.
