Optimal multithread model

Regarding the threads vs. processes discussion I see a use case which 
hasn't been discussed yet.

Consider the C10K application with many cold links and a context (i.e. 
authentication, data structures, ...) associated to each connection.

With threads we can easily set up a pool of worker threads that easily 
and efficiently pick up the context associated to the connection 
becoming active. I don't see how an equivalent model can be efficiently 
implemented with processes.

I would prefer it was possible to do it with processes because they have 
the benefit of a separate  memory space which is much better for 
security and robustness. But I couldn't find a way to do it as easily 
and efficiently as with threads.
