I'm not sure... I know it's not a very strong argument, but the Poco::Timer code is not that complex, and I could not find anything wrong with it.

What puzzles me is that the location Helgrind reports is "inside" the mutex object itself. Is it even possible to create a race on the memory location of a mutex, when only accessing it through the pthread_mutex_* API?
