In practice, almost none of the applications exhibit >this behavior. Start a background download in White Knight or Zterm, then go into Photoshop and do a 24 pixel Gaussian blur on a 20mb image. See how long your connection lasts (on a 7100/66 here - about 2.5 seconds to failure). Try the same using Zoc and ColorWorks on an OS/2 PC, not a single character dropped. Incidentally the Gaussian blur happens faster as well on a P75 w/ same Ram (48mb).
