+pthread conditions, the signal is then lost and so if you want to be sure that
+you don't miss it you must keep the mutex associated with the condition
+initially locked and lock it again before calling
+\helpref{Signal()}{wxconditionsignal}. Of course, this means that this call is
+going to block until \helpref{Wait()}{wxconditionwait} is called by another
+thread.
