		// XXX why does this fix the glitch??
		//
		// Something weird is going on here. This SHOULD be fine as a simple
		// pipe(), but for some reason, backpressure from the cache stream
		// can cause the pipeline to drop the first chunk of data, resulting
		// in invalid JSON. Until that is fixed, just write into the cache
		// without any backpressure.
		//
		// The only hazard is that, if the fs is truly very slow, and the rest
		// of the consumption pipeline is very fast, then we'll back up into
		// memory and use more than we ought to, rather than pushing back on
		// the incoming stream. However, this isn't likely to ever be a problem
		// due to how npm does HTTP. Either it's fetching a JSON response,
		// or a tarball (which is also either unpacking to disk, or streaming
		// directly to a tarball file on disk). So, if the disk is slow, and
		// it's a tarball request, we're likely to get backpressure from the
		// main pipeline anyway. It can only become a problem if the JSON
		// response is large enough to span multiple chunks, and also the fs
		// is loaded enough to start slowing down. In the JSON response case,
		// we're going to load the whole thing in memory anyway, so nothing is
		// made particularly worse by this lack of backpressure.
		//
		// It is possible that the root cause of this bug exists either in
		// cacache, minipass-pipeline, or minipass itself. But since we don't
		// do a multi-pipe tee stream anywhere else in npm's stack, this is
		// the only spot where it can make itself known.
