[rabbitmq-discuss] AMQP & Python Write-Up

[Tim Coote]

Surely one of the great benefits of a messaging programming style is  
that you can use processes rather than threads.

Threads will surely become a bottleneck as future hardware speed  
improvements move to multicore and so cannot support shared state. So,  
we can move back to the relatively safer and lower cost ($ to build  
and maintain) process based software models.

Although Python supports a threading model, the GIL makes it  
ineffective in many cases.  I suspect that this is deliberate on  
Guido's part.
