Detailed Description

A service which initializes a TBB thread pool.

This service can be configured with an array of IThreadInitTools which will each be invoked concurrently on each worker thread. A ThreadInitTask is created for each thread and given the list of tools. A boost::barrier is used to synchronize the calling of each tool concurrently on all threads at the same time.
