[mod_python] Howto force reload of all modules

Hello,

please, I'm using apache.import_module() to import my modules
in mod_python 3.2.8 (I'm stuck with this version on our
production server). Since it has its problems, please, what
is the easiest way to reload all modules?

Is there some Apache directive or some apache. method which
would allow me to ask for all modules to be reloaded
on next access?

Thank you,
Hynek Hanke
