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.

Stream implementations can and do ignore backpressure; and some spec-defined features explicitly break backpressure. tee(), for instance, creates two branches from a single stream. If one branch reads faster than the other, data accumulates in an internal buffer with no limit. A fast consumer can cause unbounded memory growth while the slow consumer catches up — and there's no way to configure this or opt out beyond canceling the slower branch.
