I know of it being used in real world hard realtime applications, so it can't be all that bad. It may not be the best or only answer so Tron may have something going for it too. Of course the real problem is that there is no truly active and progressing effort to build a usable Ada OS, so it all gets kind of academic as to whether or not RTLinux or Tron or anything else can help out in some regard.
