For both mod_python or mod_wsgi, you don't have to have it inside the
handler/application function, you can instead stick it at global scope
within the same code file and the code will be executed when the
module/file is first loaded. By default the file is loaded on first
request which targets the application. For mod_python you can force it
to load at process startup using PythonImport directive. For mod_wsgi
you can use WSGIImportScript directive. In mod_wsgi 3.0 you will also
through options to WSGIScriptAlias where you define application mount
point be able to set things so code is preloaded on process startup.

For mod_wsgi, information on reloading and how to can cause automatic
reload of application/configuration without restarting whole of
Apache, see:

  http://code.google.com/p/modwsgi/wiki/ReloadingSourceCode

In mod_python, you could use its code reloading ability, but your
configuration file would then have to be valid Python code and
couldn't be some other file format.
