A mutex is a common type of lock used to serialize concurrent access by multiple threads to shared resources. While support for POSIX mutexes in the QNX Neutrino Realtime OS dates back to the early days of the system, this area of the code has seen considerable changes in the last couple of years.

What if I told you that for most cases you don't need them? Would you believe me? What if I also told you would see dramatic increases in performance for those areas of code that had high levels of contention?

QNX only....
