[mod_python] preloading modules

You might try forcing everything to run under the main insterpreter by
sticking

PythonInterpreter main_interpreter

somehwere in httpd.conf. This way PythonImport (which only runs under main
insterpreter) and everything else will run in one interpreter and you
should see the connections (may be).

PythonImport is a flaky directive for a couple of reasons. First, there is
the subinterpreter problem. Second, the apache startup is a bit more
complicated than one may think, at the time when PythonImport is executed
(which is at child initialization time), the config has not yet been
parsed (or rather it has, but the child has no access to it yet).

The bottom line is your mileage may vary with PythonImport.
