This can cause undefined behavior: http://www.cplusplus.com/reference/mutex/mutex/unlock/ "If the mutex is not currently locked by the calling thread, it causes undefined behavior." This may potentially be the root cause of a hang (wait handle never signals) seen when creating/destroying menu surfaces while a parent does swap_buffers.
