While different implementations might in some cases be slightly more
complex than just using locks, I don't see why it should be impossible.
After all, thread-safe toolkits are not new.
Do you have any specific problems in mind?
Also, it should be noted that this feature is important: Unless we have
this or an equivalent, it will _not_ be possible to use concurrent
Haskell for writing GUI programs.
Of course, we could still agree that it is a goal, add something like
"unless it turns out to be infeasible" and then revisit the issue later.
