Come on, it's going to entirely depend on an individual application as to 
whether a thread-pool is appropriate.

I do not believe that a *good implementation* should ever do this.  MT 
programs are fidly little beasts and trying to do things like this 
transparently in the library is just inviting disaster.  The program writer 
needs to know what threads exist in the system and what they're doing so they 
can ensure that the interactions provide the intended behaviour, do not 
dead-lock, live-lock etc.
