I also expect some really nasty cases showing up when you try to rewind
a thread's bindings. E.g. if a let-binding that was originally applied
to a global variable has to be rewound (i.e. re-applied) to a variable
that has become buffer-local in the mean time.
I guess this brings up back into the core of the issue: the semantics of
thread-local dynamic scoping and its interaction with
buffer-local bindings.
