although how well Py_NewInterpreter separates each interpreter from each other, I am less certain of....though Im sure a particular subinterpreter would have to have a pretty catastrophic failure (i.e. segfault or similar) to affect the parent and/or siblings.
I am running multiple interpreters myself but it hasnt been heavily stress-tested.

I'm wondering -- and this is mostly directed to the hosting providers (Remi, Sean...) -- what are the problems with providing commodity-level hosting for Python programs? I can think of some, but I'm curious what you've encountered and if you have ideas about how to improve things.
Some things I've thought about:
* Long running processes are hard to maintain (assuming we rule out CGI). Code becomes stale, maybe the server process gets in a bad state. Sometimes processes becomes wedged. With mod_python this can effect the entire site.
* Isolating clients from each other can be difficult. For mod_python I'm assuming each client needs their own Apache server. Maybe this isn't as much of a problem these days, as virtualizing technologies have improved, and multiple Apache processes isn't that big of a deal.
* Setup of frameworks is all over the place. Setting up multiple frameworks might be even more difficult. Some of them may depend on mod_rewrite. Server processes are all over the place as well.
But I don't have a real feeling for how to solve these, and I'm sure there's things I'm not thinking about. How do you guys do it now, and if you could change this stuff -- on any level, from interpreter to framework -- what would you do?
