[boost] [threadpool] new version 16: pining of processors (processor affinity)

Hello, I've uploaded a new version (16) to boost vault. In the new version as much worker-threads are created as boost::thread::hardware_concurrency() returns if no poolsize is specified in the pool constructor . Each worker-thread will be pined to one processor. Currentyl supported platforms for processor pining: Windows, Linux, HP/UX, AIX, IRIX, Solaris. regards, Oliver
