Hey, that's neat. I hadn't seen that before.

FWIW the main reasons we use Apache/mod_wsgi (aside from it being a 
recommended deployment model) are the plethora of features available in 
Apache, including mod_auth_kerb, mod_cosign, and various other 
authentication handlers.

Does the Twisted/Django integration run multi-threaded or multi-process? 
Because the latter obviously dodges the GIL, the former not.

I should add it's a really rather good web server, and is very useful if 
you don't want to worry about thread/process pool size issues with 
long-running requests. This is where Twisted shines; want 500 
simultaneous XMLRPC requests which wait on a 10-20 second timeout, but 
not a thread/process pool 500-big? Easy.

That I did know about, but had forgotten - thanks for pointing it out.
