[mod_python] Force reload?

If you are using a unix-box, the easiest way would be to "touch" the handler 
file. Try adding this line at the top of the handler() function in the 
handler file. But I didn´t tested this and it is really quick and dirty. 

os.system("touch " + __file__)

On my system the handler calls this method on each request:

def reload():
    for k, v in sys.modules.items():
        if v:
            try: path = v.__file__
            except: continue            
            userpath = os.path.dirname(__file__)
            if path.startswith(userpath):
                del sys.modules[k]

This will force to reload all of my "custom" modules (nothing 
below /usr/lib/python). My handler is saved in the toplevel htdocs directory. 
This will slow down the whole request, so you should only use it in 
development-stage.

Hope it helps!
