The way to do this is to import a module that establishes the database
connection. Since the module will only get imported once the first time
and remain for as long as the process lives, there is your persistent
database connection.

At this point I do not have cleanups yet, they are coming in the future
versions, so there is no terminator function - you just let the process
die.

You can use ZPublisher, but not Zope databases.

Unfortunately, the Zope database locking is not suitable for simultaneous
access by multiple processes. May be existance of mod_python will not give
the Zope developers enough incentive to implement that.

pyapache != mod_python

Yes and no. The idea sounds good, but this sort of thing doesn't belong in
mod_python. Some time soon I will create a section on the website for
"third party" mod_python handlers - this could be one of them.
