A purely anecdotal, ancient-history lesson: about 4-5 years ago, I found
that mod_python + Quixote was quite flaky under load. Particularly, it
tended to result in a high percentage of dropped client connections, and
ocassionally in hanging Apache! (I think the server-hang was on win32
only, but I don't remember for sure). I think the problems were
attributable to mod_python, more than to Quixote or the
Quixote/mod_python connector.

In that round of tests, I chose SCGI over mod_python purely because
Apache+SCGI did a better job of managing multiple concurrent requests
under heavy load (even when the number of SCGI processes was low),
though mod_python seemed to perform as well as SCGI under smaller loads.

No matter what you choose, be sure to pound on it ocasionally, as hard
as you can, to see how your selected tools work when the going gets
tough (unless its guaranteed never to become a high-demand application).
