What's a fairly concise description of the issue at hand? I haven't been
paying much attention to this thread, and the descriptions I have seen have
been somewhat confused.

One admittedly unhelpful observation is that when something goes wrong in
this area, it's usually due to pilot error (either on the part of whoever
wrote the Haskell library, or its user), and not so often caused by a bug in
the underlying platform.
