You got a lot of long-winded replies, but the short reply is that
Twisted has packaged solutions for this. See 
http://twistedmatrix.com/projects/core/enterprise

  "Twisted provides an interface to any Python DB-API 2.0 compliant 
database through an asynchronous interface which allows database 
connections to be used, and multiplexed by multiple threads, while still 
remaining thread-safe for use with Twisted's event-based main loop. 
Twisted Enterprise provides these services by leveraging Twisted 
Internet's utilities for managing thread pools and asynchronous 
programming."
