[mod_python] Persistent objects in sub-interpreters

Hi all,

The whole "raison-d'etre", if you pardon my french, of modpython is to
enable persistent (across request) objects like database connections, in
order to dramatically improve performance compared to solutions where each
request invokes a new interpreter, database connection, etc. At least that's
what I gather from the documentation.

However, I cannot find a documented way of holding objects for reuse between
requests to the same Python subinterpreter instance. (Perhaps I just missed
it?)

How is this done? E.g. how would I make a handler that counts the number of
invocations of itself by storing an integer in the context of its own
sub-interpreter?

Then, how do I build a persistent database connection on top of that?
