Forgetting releaseLock() permanently breaks the stream. The locked property tells you that a stream is locked, but not why, by whom, or whether the lock is even still usable. Piping internally acquires locks, making streams unusable during pipe operations in ways that aren't obvious.

Unai Emery has seen most things in this game but he has never won at Wolves. In three and a half years at Villa, he has lost two and drawn one of his three games at Molineux. Twelve months ago they lost this fixture 2-0 and this week Emery shared his poor record to stress the difficulty of the challenge facing his side, particularly given they have won just one of their past five matches in all competitions. Emery even mentioned his visit to Wolverhampton with Arsenal in 2019, when his team trailed 3-0 at half-time and lost 3-1. For Emery, there is no better time to break his duck, with the schedule dictating that Villa could move nine points clear of fifth-placed Chelsea, who visit Villa on Wednesday, before Liam Rosenior’s side travel to Arsenal on Sunday. Victory would enhance Villa’s chances of returning to the Champions League but also pile pressure on direct rivals. Ben Fisher
