There has been some discussion that these hung states could be "fixed", but that's absolutely positively incorrect.
That's one of the things I asked a few messages ago. Some people on the list were saying that it'd be "really hard" and would "require a lot of bookkeeping" to "fix" permanently-D-stated processes... which is completely different than "impossible."
Nothing is "impossible". Cracking SHA-256 isn't "impossible", it just takes more computing power than exists on the face of the planet.
Call it "infeasable" if you like. It's theoretically possible, but the amount of work and the overhead involved just are not realistic. And then you have the likelihood of a bug in the bookkeeping code leading to runtime corruption... Better to take the hit now and fix the original problem.
