[mod_python] mod_php vs mod_py - include vs. import

be careful though; there are some hidden gotchas lurking in this solution.
for example, if you reload a module defining some base class, but don't
reload all modules defining subclasses of that base, then the base class
object will no longer be the same as the corresponding base class object
in the __bases__ list for subclasses, and isinstance(sub, base) will fail
(leading to other failures, like the new builtin 'super' won't work
properly).

i did a lot of head scratching before i figured this out; but if all
you're reloading are static configuration modules exporting simple things
like constant immutable string or numeric variables, you should be ok.

cheers,
