=begin
 While tracking another issue with ConditionVariable, I realized that ConditionVariable#wait assumes that the waking-up side (#signal and #broadcast) will remove the thread from the list of waiters.
 
 Unfortunately, Mutex#sleep may return right away if an interrupt is set for the thread, in which case the thread will stay in the condition variable's waiting list.
