I have a mind to see if a solution inspired by the WTF::Lock solution (see
https://webkit.org/blog/6161/locking-in-webkit/ ) to see if QWaitCondition
performance would improve and if we could get rid of the ugly freelist backing
QMutex on non-futex platforms.
But if I can't get benefit for QWaitCondition, then I won't bother. Platforms
without futex will suffer and people should just get a better OS instead (like
Linux or Windows 8).
