Hi Derek I think that your hard drive is failing. Is it a SSD? If no, it's typical of an old failing hard disk. Could you try to mount a mfs filesystem and see if your example makes a pause? That should not trigger any disk read as it's an in-memory filesystem, if it doesn't block that mean that the hard disk is failing.
