There's no need to recreate dbpool, basic reconnecting logic is already 
there, if you look in SVN.

Specifically, look at the ConnectionPool class: There are two kwargs 
that you can pass, cp_reconnect and cp_good_sql.

I use this version in production as part of a simple database uptime 
monitor, and it works in a satisfactory manner.  You may need to trap 
ConnectionLost errors in some cases, in order to re-send your original 

Hope this helps,
