Goodness! So, in my mod_python applications I often acquire database handles 
and store them in objects outside of the handler() function so that they 
persist between requests. (This is to avoid the expense of acquiring a new 
handle for every request). I then use a cleanup() function to release those 
database handles.

The implication of this is that I will no longer be able to release the 
handles at server shutdown, yes? Can anyone suggest an alternative method of 
doing this? Are there any Python tricks where you can execute code when the 
interpreter itself is about to stop? Or could I have a Python script running 
in another process which "looks in" to the mod_python process and 
periodically cleanly releases database handles?

Cheers,
Richard
