This change keeps a heavily weighted average of the wait times under 1.5ms (1.5 times the max spin threshold), and adjusts the spin time to be 150% of the average wait time. Introduce spin time adjustments when spin locking works, and adjust to between 150% of the average wait time and the maximum threshold. Reviewed-by: joao

The new approach will quickly reduce the amount of allowed spinning time when it detects that lock contention is resolved by waiting instead of spinning. We get better results by dynamically adjusting for elapsed running time instead of trying to fine tune iteration counts that won't work for all CPU types, speeds, etc. From observation, lock performance suffers if the spin time is higher than the minimum wait time. Because of this, QMutex never increases the spin time, it only reduces the spin time to the minimum observed wait time. For very long wait times, we disable spinning completely (and always resolve contention by waiting). Use QThread::yieldCurrentThread() when spinning on a contended mutex. Comment from the code: be a good citizen... yielding lets something else run if there is something to run, but may also relieve memory pressure if not. Reviewed-by: joao

This makes QMutex perform more or less identically the same as pthread_mutex_t when contended. We have to use the contender count in a different way due to the way that futex() waiting works. Waiting on a futex atomically checks that the value has not changed from the expected value and then puts the thread to sleep. So, on Linux, the contender QAtomicInt will only ever be one of three values: 0 for unlocked, 1 for locked, 2 for contended. This does mean that there is a slight chance for unfairness due to the fetch-and-store to zero in the wakeUp() function, but unfortunately this cannot be avoid as the code is now. Reviewed-by: joao

On UNIX, with monotonic clock support we get full nanosecond resolution, microsecond otherwise. On Windows we convert the performance counters to nanoseconds if availble, otherwise we only have millisecond resolution. On Mac, the mach time is converted to nanoseconds. On Symbian, we have microsecond resolution. Reviewed-by: joao
