Feature #7086: ConditionVariable#wait has meaningless return value

I consider this an API bug: when invoked with a timeout value the caller cannot distinguish from the return value whether the condition has been signaled or the time has run out.  Consider how Java does it: http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/locks/Condition.html#await(long,%20java.util.concurrent.TimeUnit) and http://docs.oracle.com/javase/7/docs/api/java/util/concurrent/locks/Condition.html#awaitUntil(java.util.Date)

There's another issue exhibited through the script but I will create a separate ticket for this.
