 From a quick look at one paper on this subject it appears to be an 
attempt to solve the problem where there are more connections than the 
language will allow you to have threads.

Erlang suffers from the opposite effect - it can have many more threads 
than the OS will support IO handles !

I suggest you scrap such thinking (be it object oriented or "thread 
pools") and go with the Erlang way (one process for every concurrent 
activity).

<aside>
"Thread pools" can be useful in Erlang, but mostly for writing clients 
which need to maintain a pool of sockets to other systems which are 
either non multiplexed or have other problems in this area
