In the current version, by calling
ws.originalEndbefore cleaning up remaining data, afinishevent is emitted which can cause problems if the user's code assumesfinishmeans no more work will be done. I ran into this with pump, which will destroy a stream as soon as it gets a finish/close/end. Thus, the earlyfinishwas swallowing errors which would have otherwise been reported. Seems probable that, without this fix, the last flush of data could be accidentally blocked.
