I have a one thread per connection version and it works fine, however it
uses a lot more memory, not to mention all the threads use up stack space
and then there are memory manager issues with threads. I am not convinced
one thread per connection is going to scale well for something like a
instant message server where you have lots of long term connections that
sit idle most of the time.
I could also use a thread pool with each one handling 64 connections.
The other thing is while using select might be slower I don't think it
would be noticeable to users because of network latency.

Virtualization & Cloud Management Using Capacity Planning
Cloud computing makes use of virtualization - but cloud computing
also focuses on allowing computing to be delivered as a service.
