Normally modules are not reloaded because they are cached by python. web2py
can bypass this, depending on where the modules are located. If you kwwp in
your modules in the web2py app/modules folder then you can do in your
models/db.py
DEBUG=True
from gluon.custom_import import track_changes; track_changes(DEBUG)
This will reload your modules when they change/
