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). -- Thiago Macieira - thiago.macieira (AT) intel.com Software Architect - Intel Open Source Technology Center _______________________________________________ Development mailing list Development@qt-project.org http://lists.qt-project.org/mailman/listinfo/development
