For this sort of application, you might want to consider using a 
threadpool.  You can either use one provided by your target OS API, or 
use Boost.Asio.

You can ignore most of the I/O stuff and just use an io_service as a 
threadpool manager by giving it an io_service::work so it doesn't stop 
until you're done, feed it as many threads as you want to concurrently 
run work, and then just post jobs to it whenever something comes up.
