advanced usage of python threads

[hyperboreean]

Well, I will be writing the application server of a three-tier 
architecture system. I will be using Twisted for the communication with 
the client but from there I have to make several calls to a database and 
this asks threading. The tables will be filled by another system that 
gathers some data. I want to implement several threads (workers) that 
takes care of each client and a coordinator thread that takes care of 
all the threads. But I have never worked with threads at this level and 
I feel like I need some coordination. I will be thankful with 
documentation on advanced threads, I probably can apply that in practice.

Thanks to all.
