Great idea! You have "check and act" problem in ContinuationWait, though. You check if (completed) and if not then you assign continuation and wait. However, after you've checked that it is not complete and before you've set attachedContinuation = c, your original continuation could have resumed and saw that attachedContinuation is still null.(so you'll loose the signal and will never resume)
