That's "Webware for Python", by the way. ;-)

As far as I know, several threads are instantiated on startup and when
a "request path" is resolved inside one of those threads, the servlet
factory creates a servlet instance which I would hope would stick
around after the request has been processed. Having said that, I
wasn't sure whether this was implemented within the framework itself,
and when I wrote my own servlet factory once, I decided to implement
"instance caching" within that factory.

I don't know whether other servlet factories implement caching
themselves, although a quick glance at the PythonServletFactory class
indicates that some kind of cache is in use.

Per-servlet-factory-instance (ie. per-thread) caches seem to be used.
One of the Webware mailing lists (webware-discuss, perhaps) might be a
better place to ask these kinds of questions, though.
